Blue hair gives a Halloween costume a head start, because the colour already reads as fantasy before you've added a single other piece. I treat it as the anchor. If you already wear cobalt, navy, turquoise or pastel blue, the right character makes it look planned, and if you're borrowing the colour from a wig for one night, the same rule applies. The list below runs from animated heroines and anime characters to sea creatures, space looks and easy DIY ideas, with Coraline and Sailor Mercury as the simplest starting points and the original looks giving you more room to play. For each one I've covered clothing, hair, makeup, props and the shoes I'd actually walk in, so the wig isn't doing all the work.

Wig, Spray or Real Dye for One Night
If your hair isn't blue already, there are three honest routes, and each one behaves differently over a long evening. This is how I'd weigh them before buying anything else for the costume.
A wig, for most people
A wig gives the cleanest colour and the exact cut a character needs, which is why most of the looks below assume one. Check the label for heat resistance before you go near a curling iron, and keep any wig away from candles, oven doors and fire pits, because ordinary synthetic fibre frizzes and can melt. Fit it over a wig cap pinned into your own hair or a grip band so it doesn't creep backward. A cheap wig sheds loose fibres on its first wear, so give it a shake and a gentle comb-out at home first.
Temporary colour spray
Spray-in blue is fine for an hour or two on light hair, but it rubs onto collars, hoods, pillowcases and anyone you hug, and rain turns it streaky. I only suggest it for a short event, sprayed with an old towel over your shoulders and left to dry fully. On dark brown or black hair it barely shows unless you go heavy, and heavy feels crunchy.
Semi-permanent dye
Real blue dye needs pre-lightened hair to look bright, and it fades over the following weeks, often drifting toward teal or green, especially on yellow-toned blonde. It also stains towels and grout. Treat it as a hair decision you'll live with well into November, not a costume accessory.
1. Coraline Halloween Costume

Coraline's rainy-day outfit is the one I'd send a first-timer to, because three pieces carry it: a bright yellow hooded raincoat, a red-and-white striped shirt underneath and a short cobalt bob. A dark pleated skirt follows the film more closely, while straight-leg jeans are kinder on a cold night. Clip one side of the bob back with a small dragonfly clip; it's a tiny detail, but it's the one people point at. Keep the makeup to freckles, rosy cheeks and a natural pink lip, and carry a blue messenger bag or a plush black cat. Yellow rain boots genuinely earn their place on a trick-or-treat route. I'd skip button eyes on your face entirely and glue decorative buttons to a pair of empty frames you can pull off when you need to see the curb.
2. Joy Halloween Costume

Joy is mostly a yellow dress and a good wig. I look for a loose knee-length skater dress so you can move, then add small blue flowers with removable fabric stickers or washable fabric paint rather than anything permanent. The electric-blue pixie wig matters more than the rest: brush the front up and out, and set it with hairspray held well back, because synthetic fibre goes stiff and shiny when you spray too close. Peach blush, gold shadow, mascara and a glossy pink lip keep the face fresh. Blue flats or clean white sneakers will last the evening. A clear craft ornament or painted foam ball makes a light memory orb, and the yellow-and-blue pairing does the recognition work without theatrical makeup.
3. Sadness Halloween Costume

Sadness is one of the cosiest costumes here, which is a real point in her favour on a cold October night. An oversized white or pale gray turtleneck, navy cropped pants or leggings and simple blue flats give you the base. The chin-length dark-blue bob needs a neat curved fringe; I trim wig bangs a little at a time with the wig on a head form, since they always look longer than they are. Big round glasses finish the face. Light blue makeup over the face and neck reads well, but it rubs straight onto that white turtleneck, so if you don't want to babysit your collar all night, blue tights and gloves give a similar effect. Carry a blue memory orb, a small tissue box or a blue notebook.
4. Sailor Mercury Costume

If your hair is already short and blue, Sailor Mercury is half done before you start. The uniform is a white sailor top with a royal-blue collar and matching pleated skirt, a pale blue front bow, a darker bow at the back, elbow-length white gloves and a slim blue choker. Bows are where homemade versions slip: a floppy bow looks tired by ten o'clock, so I back mine with stiff interfacing or a strip of felt. A navy or sapphire bob with soft bangs, cool blue shadow, soft pink lips and red stud earrings handle the rest. Choose blue ankle boots over knee-highs if you'll walk a lot, and carry a small visor, pocket notebook or compact handheld device. She slots straight into an anime group.
5. Hades Halloween Costume

Hades is all about the hair, and tall blue flames are harder to build than they look. I start with a structured electric-blue wig, or I lift a long wig upward over a little padding and pin it with concealed clips; without that internal support the fibres flop forward within an hour. Underneath, layer gray robes, a charcoal tunic and a long black or smoky blue draped coat, cinched with a wide gray sash so the shape doesn't turn into a blanket. Pale gray-blue face makeup, sharp brows, smoky eyes and a playful dark grin carry the character. Blue LED hair clips or sheer blue fabric over the shoulders suggest flame without anything hot. Black boots keep you steady under the robes, and a medallion, blue gemstone ring or rolled parchment covers the prop.
6. Marge Simpson Halloween Costume

Marge only works if the hair is enormous, so I'd spend your money on a tall royal-blue beehive wig with a secure inner cap and keep everything else simple. A strapless or sleeveless green midi dress, flat red shoes and a chunky red beaded necklace give you the palette. Tall wigs pull backward as the night goes on; a skin-safe wig band plus a few pins anchored into your own hair stops that. Yellow face and body makeup is very hard to apply evenly across arms and neck, and it comes off on everything you touch, so I'd honestly reach for yellow tights and long gloves instead. Keep the eyes minimal with soft rounded lashes drawn around them, and carry a grocery bag, toy rolling pin or small handbag.
7. Thing 1 Costume

A red base and a fluffy wig are all Thing 1 needs, which is why he's so quick to pull together. Wear a bright red long-sleeve shirt with red joggers or leggings, then add a white felt circle on the chest lettered with 'Thing 1' in black. Here's the catch: felt glued onto a polyester shirt peels at the edges after a few hugs, so I stitch around the circle with a quick running stitch, or use fusible web on a cotton shirt. A turquoise-blue wig gives the wild shape, and naturally curly blue hair can be brushed up and fixed with temporary product. Rosy cheeks, blue mascara and a few freckles keep it playful. White gloves and red or white sneakers are fine for dancing, a friend can become Thing 2, and a small red-and-white striped hat makes an easy photo prop.
8. Corpse Bride Costume

This is Emily from Corpse Bride kept on the gentle side, ghostly rather than gory. A thrifted white, silver or pale blue maxi dress with lace sleeves is the base, with a sheer gray-blue veil, faded faux flowers and some tulle draped at the shoulders. I age the dress by brushing gray eyeshadow into the folds instead of tearing it; you get the faded look and can still wear the dress again. A long wavy blue wig with a side part and slightly tousled ends suits her, along with light blue face makeup, lavender shadow, defined lashes and a cool-toned lip. Skip painted wounds and bloodstained fabric. Pale blue ballet flats or low lace-up boots go under the hem, and a light bouquet of blue roses is the only prop she needs.
9. Evie Halloween Costume

Evie mixes deep blue, black and red, and the trick is keeping red to accents so the blue hair stays the headline. I'd layer a fitted blue jacket or moto-style vest over a red-and-blue printed top, then add dark blue leggings with removable red heart patches. A long navy wig with loose curls should fall past the shoulders. Curled synthetic wigs flatten when you lean against a car headrest on the way there, so pack a wide-tooth comb to lift them again. Smoky blue shadow, defined brows, rosy blush and berry lipstick keep her glamorous but wearable. Black low-heeled ankle boots, fingerless gloves, a gold crown necklace and a heart-shaped compact finish her off, and a studded belt adds texture. She sits well in a group of storybook and fantasy-school characters.
10. Ramona Flowers Costume

Ramona Flowers is the costume I'd build almost entirely from your own wardrobe. A dark utility jacket over a striped T-shirt, black shorts or a simple mini skirt and opaque tights cover the clothes. The vivid blue bob with choppy bangs is what turns you from a person in a jacket into Ramona, so put your effort there. Black lace-up combat boots handle walking between parties. Keep the makeup casual: smudged liner, muted pink lipstick, a touch of cool blush. A round messenger bag with a simple star patch nods to the comic, and a takeaway coffee cup or small parcel stands in for her oversized hammer. On a cold night I'd wear a hoodie under the jacket; it suits her relaxed graphic-novel look anyway.
11. Hatsune Miku Costume

Miku's twin tails are the whole silhouette, and they're also the part that gives people trouble. A sleeveless silver-gray blouse with turquoise trim, a pleated black mini skirt and a slim turquoise necktie form the base, plus detached black arm sleeves, over-the-knee black socks and black platforms or ankle boots. Very long aqua wigs tangle at the ends as they brush your back, so I mist them lightly with diluted fabric softener before the night and detangle from the bottom up. Split the wig into two high ponytails held with square black-and-pink accessories. Turquoise liner, fluttery lashes and glossy pink lips suit her. A headset microphone, glow stick or small music controller works as the prop. Flip the tails behind your shoulders in crowds, because they catch on bags and door handles.
12. Jinx Halloween Costume

Two very long braids make Jinx, and those braids are heavier than people expect. I'd choose an extra-long electric-blue wig and band each braid in several places from top to bottom so it doesn't unravel while you move. For clothes, a fitted black crop top or tank with striped plum pants, a belted utility skirt and fingerless gloves keep her mismatched look; swap in opaque layers if you want more coverage. Arched brows, rosy shadow, strong liner and berry lipstick handle the face. Paint her blue arm patterns with skin-safe makeup and press powder over them so they don't smear onto your sleeves. Chunky black lace-up boots balance the hair. A small mechanical-looking backpack or gemstone pouch replaces any weapon props, which keeps you light and welcome at public events.
13. Bulma Halloween Costume

Bulma is a good outdoor pick because nothing about her is restrictive. A bright pink T-shirt dress, or an oversized pink top belted over fitted shorts, gives you the base, with a red neck scarf, purple knee socks and red sneakers or lace-up boots. The short turquoise bob with side-swept bangs sells the anime reference; make sure the bangs sit clear of your eyes, because wig fringe that grazes your lashes gets irritating fast. Peach blush, black liner, mascara and bubblegum-pink lipstick suit her. I like stitching a small name patch onto the chest or sleeve so people place her quickly. A canvas utility belt holds your phone and keys, and a toy gadget, capsule-shaped container or small backpack covers the prop. Breathable separates and flat shoes make her easy to wear for hours.
14. Rei Ayanami Costume

A clean white base and sharp panel shapes are what make Rei Ayanami, so the neatness of those panels decides how good she looks. A fitted white jumpsuit, or a long-sleeve top with matching leggings, is the base. Cut the black and red geometric panels for the shoulders, chest and thighs from removable vinyl or felt, and I'd draw a paper template first so both sides match. White low-heeled ankle boots finish the bottom half. The pale powder-blue bob should sit close to the jaw with wispy bangs, and a fitted black headband under the wig helps if it slips. Keep the makeup understated with a light base, subtle pink shadow, fine liner and muted rose lips. Skip red contact lenses; a reddish shadow suggests the eye colour with nothing in your eyes. A slim wrist device or white structured backpack completes the pilot.
15. Wendy Marvell Costume

For anime fans who want a modest, comfortable costume, Wendy Marvell's palette is cheerful and forgiving. Start with a sleeveless maroon dress with pale yellow trim and a gently flared skirt, with fitted shorts underneath so you can move freely. Blue or black ankle-strap sandals suit a mild night; flat ankle boots suit a cold one. The long navy wig is worn straight with a center part and two small sections framing the face. Long straight wigs fly about with static on dry evenings, and running a dryer sheet lightly over the surface calms them. Pink blush, brown liner and a soft berry lip keep her youthful, and a gold wing-shaped clip near one temple adds the detail fans look for. A small book, guild-style patch or blue drawstring pouch replaces battle gear, and a cream cardigan won't spoil the maroon-and-blue combination.
16. Aqua Anime Costume

Aqua's outfit has a lot of layers, and the bows are where I'd put my sewing time. Start with a royal-blue sleeveless mini dress trimmed in white and gold, with a large green bow at the chest and a smaller matching one near the waist. White detached sleeves and blue over-the-knee socks build the anime silhouette, finished with blue boots or white flats tied with blue ribbon. The long sky-blue wig goes into a high ponytail with a round blue ornament. An ordinary wig pulled up high shows the wefts at the nape, so I'd buy one sold as a ponytail wig or clip a separate ponytail onto a short base wig. Aqua shadow, defined lashes, bright blush and glossy pink lips suit her. A folding fan or a clear bottle of blue confetti makes a water-themed prop, and opaque fabric with hidden shorts gives dependable coverage.
17. Rem Maid Costume

Rem's maid dress depends on a crisp apron and collar, so I'd press both before anything else. Look for a black or dark navy knee-length dress with puff sleeves, a white ruffled apron and a structured collar, then add white knee socks and black Mary Janes or low block heels. The short powder-blue bob has bangs swept across toward one eye; keep them just long enough to angle over the brow so you can still see where you're walking. A white lace headband with small pink ribbon details sits on top. Matte foundation, pink blush, fine liner and rose lips keep her soft, and blue mascara echoes the hair. Carry a small tray with faux pastries, a teacup or a folded hand towel. Before you commit, check that the shoulders and waist let you sit down and lift your arms.
18. Esdeath Costume

Esdeath can look dramatic with no weapon at all if the jacket is right. I'd find a fitted white button-front jacket with structured shoulders and add black trim you can remove later. Pair it with white trousers or an opaque knee-length skirt, black tights and white knee-high boots, plus a black waist belt, dark gloves and a small blue gemstone brooch at the collar. White pieces show every smudge, so do your makeup before you dress and keep a stain pen in your pocket. The very long icy-blue wig with straight ends and side bangs is her defining feature. Cool gray shadow, crisp winged liner, sculpted blush and a muted berry lip suit her face. An ice-crystal clutch or clear acrylic snowflake stands in for the sword, and a flexible jacket rather than stiff armour keeps her easy to wear at an indoor party.
19. Chloe Price Costume

Chloe Price is a thrift-store build. A black graphic tank or T-shirt under an open gray vest, distressed-look jeans with opaque patches behind any holes, black lace-up boots, a long necklace and stacked bracelets cover her. The short bright-blue wig wants uneven layers and a grown-out look; I rough it up with my fingers instead of combing it smooth, because a neat wig reads as costume-shop rather than Chloe. Charcoal shadow, black liner and muted pink lipstick give the smoky face. Her arm tattoo can be drawn on, but blue arm sleeves or printed fabric cuffs skip the body paint altogether. A vintage-style instant camera or small blue backpack makes a safe prop, and a plaid shirt tied at the waist is a layer you can pull on when it gets cold.
20. Lapis Lazuli Costume

Lapis Lazuli is one of the friendlier fan-made costumes because a flowing blue dress does most of the job. I'd choose a sleeveless royal-blue skater dress, add a deep navy bodice panel and tie a light-blue sash at the waist. Matching blue tights and ballet flats or ankle boots go underneath. Her short navy wig needs rounded volume and side-swept bangs, which a cheap wig won't hold unless you tease the roots a little. Light blue face makeup works, but gloves and tights are far less upkeep. Navy liner, pale aqua shadow and long lashes keep the eyes expressive. Her large teardrop gem belongs on the upper back; fix it with fabric-safe adhesive and give it a full night to cure before you wear it. Translucent blue panels worn like a soft cape suggest her water wings, and a clear water-drop ornament or small mirrored pouch makes the prop.
21. Blue Diamond Costume

Blue Diamond is a monochrome costume, so every blue should sit in the same family or the effect falls apart. Start with a long navy gown with structured shoulders and a softly draped skirt, and layer a pale blue sheer cape from the head or shoulders, cut so it frames the face without blocking your view. A waist-length powder-blue wig is styled into her smooth, pointed shape with the side sections kept under control. I use blue face makeup sparingly and blend it down the neck, though a pale blue bodysuit under the dress is easier to clean up. Navy shadow, shimmer and small teardrop gems beneath the eyes give the elongated look. Long blue gloves, navy boots hidden by the skirt, a light diamond-shaped chest piece and a clear crystal clutch finish her without fussy props.
22. Blue Mermaid Costume

A blue mermaid built from separates is far easier to wear than a fishtail, and I'd steer most people that way. A turquoise scale-print maxi skirt with real stretch lets you walk, and an iridescent blue long-sleeve top with shell appliqués and a sheer aqua wrap at the waist finishes the body. Wear long blue hair in loose waves, or decorate a wavy wig with pearl clips and faux seaweed ribbon. Aqua shadow, pearl highlighter, glossy lips and a few scales by the temples complete the face; I stamp the scales through a scrap of fishnet with a makeup sponge, which is much quicker than drawing each one. Flat blue sandals or hidden sneakers beat a tight hem. A shell purse or starfish wand covers the prop, and skirt length and makeup intensity adapt easily for teens.
23. Blue Fairy Costume

The blue fairy is light to wear, which matters on a long evening. A sky-blue dress with a fitted bodice and layered knee-length tulle skirt, silver tights and pale blue ballet flats or glittery ankle boots give you the base. A pastel-blue wig in a loose braided crown with a few curls left around the face suits her. Lavender-blue shadow, rosy blush, pearl highlighter and tiny silver gems at the outer corners of the eyes add the sparkle. Wing straps are what I check first: elastic that cuts under the arm is miserable after an hour, so I wrap it in soft ribbon or wear the wings over a fitted cardigan. Keep the wings compact if you'll be in crowded rooms. A floral headband, drawstring pouch and ribbon-wrapped wand finish her.
24. Ice Queen Costume

An ice queen lets platinum-blue hair do most of the talking. I'd look for a pale silver-blue maxi gown with long sheer sleeves, a fitted waist and a skirt full enough for a normal stride, then add a white faux-fur shoulder cape and a delicate crystal-style crown. Faux fur sheds onto everything nearby, so shake it hard outdoors and go over it with a lint roller before you put it on. The hair can be straight, waved or in a thick side braid. Frosted blue shadow, silver liner, pale pink blush and lip gloss keep the face luminous. White or silver ankle boots under the hem add warmth and grip. Carry a snowflake ornament or an acrylic scepter with no pointed edges, and add crystal earrings and a gemstone belt. There's no heavy face paint or complicated construction involved.
25. Blue Witch Costume

A blue witch is what I suggest to anyone tired of the all-black version. Start with a navy velvet midi dress and a cobalt cape over the shoulders, then add striped blue-and-black tights, silver-buckled ankle boots and a wide-brim pointed hat wrapped in turquoise ribbon. Wide brims and long wigs fight each other, so I pin the hat through the wig into a small braid of my own hair underneath and it stops sliding back. Long blue waves or a low side braid with silver star clips both work. Navy smoky shadow, shimmery blue liner, plum lipstick and a little highlighter keep it playful. A small broom or a fabric-covered book painted with stars and moons is the prop, kept storybook rather than ceremonial or frightening. A crossbody pouch under the cape holds your essentials without breaking the blue silhouette.
26. Blue Alien Costume

An alien is the most forgiving costume here because there's no canon to match. Wear a metallic silver jumpsuit, or a fitted silver top and wide-leg pants, with a translucent blue belt, white platform sneakers and reflective wrist cuffs. Metallic fabric has little give and shows strain at the seams, so I size up a little and make sure you can sit down comfortably before the night. Electric-blue hair works in a high ponytail, blunt bob or two sculpted space buns. Keep blue face makeup to the temples instead of the whole face, with silver liner, iridescent shadow and small adhesive gems. An antenna headband is optional retro fun. A clear sphere purse or light-up wrist device makes the prop, and reflective tape along the seams adds a sci-fi edge while leaving the jumpsuit flexible.
27. Galaxy Space Traveler Costume

Deep blue hair and a galaxy theme belong together. I'd start with a navy boiler suit, which is warm and full of pockets, and decorate it with removable silver stars and purple nebula patches. A metallic utility belt, fingerless gloves and sturdy silver sneakers suit the traveller idea. Keep the hair practical in a long ponytail or braid under a clear visor headband. Violet shadow, blue liner, pearl highlighter and tiny white stars along the cheekbones handle the makeup; I dot the stars on with the handle end of a brush dipped in white liner. Cover a light backpack in silver fabric, add a homemade mission patch with generic wording, and carry a clear bottle of silver confetti. Of everything on this list, this one copes best with a cold outdoor event.
28. Blue Pop Star Costume

A blue pop star look comes down to restraint with the sequins. Pair a silver sequin jacket with a cobalt crop top or fitted tank, then add metallic wide-leg pants, a pleated skirt with shorts under it, or blue faux-leather trousers. I'd keep sequins to one or two pieces; more than that reads as clutter in photos, and sequined seams scratch the inside of your arms all night. White platform sneakers let you dance. Style long electric-blue hair in a high ponytail with braided sections and sparkly clips. Blue winged liner, silver shadow, rosy blush and glossy lips give you a stage face. A headset microphone, star-shaped sunglasses and stacked silver bracelets suggest the performance, and a small belt bag holds your things. Because it's an original character, you get the glamour without impersonating any real singer.
29. Blue Punk Rock Costume

Bright blue hair looks most at home in a punk costume, so this is an easy one to own. Start with a black band-style T-shirt, a blue plaid pleated skirt or slim black jeans and an oversized faux-leather jacket. Add opaque tights, striped socks and chunky lace-up boots. Short blue hair can go into spikes, a faux hawk or messy waves with temporary styling paste. Smudged black liner, cobalt shadow, strong brows and dark berry lipstick handle the face. I personalise the jacket with pinned patches and clip-on chains, so nothing gets sewn or punched through that you can't undo the next day. A small guitar-shaped purse or handheld microphone makes a safe prop. If the party is outdoors, a black thermal top under the tee keeps you warm without changing the look.
30. Blue Crayon Costume

The crayon is the cheapest build on this list and the one I'd hand to anyone with an afternoon and some felt. Wear a royal-blue T-shirt dress, sweatshirt dress or blue top and pants. Cut wavy wrapper lines from black felt for the chest, waist and sleeves, plus a vertical label down the front that doesn't copy any brand's graphics. Hot glue on knit fabric pops off when the shirt stretches, so I stitch the felt at each end or use fabric glue and let it dry overnight. Make the pointed tip from blue poster board on a soft headband, never with a tie under the chin. Let a blue bob or your own hair show beneath. Blue liner, rosy cheeks and clear gloss are enough makeup. Blue tights, matching sneakers and a sketchbook with an oversized cardboard drawing finish it, and it suits school, office and family events.
31. Blue Jellyfish Costume

A jellyfish turns a clear dome umbrella into the costume, with blue hair as the bonus. Wear a pale blue tunic dress over shimmery leggings, plus silver sneakers or light blue rain boots. Keep the hair up in a high bun or a short wavy bob so it doesn't compete with the canopy. Decorate the umbrella with translucent blue fabric, ribbon tentacles and battery fairy lights in cool white; I tape the battery pack to the shaft just under the canopy so its weight doesn't drag the lights loose. Keep every ribbon short enough that it can't wrap around your legs. Aqua shadow, pearl highlighter and small iridescent gems give a watery face. Hold the umbrella overhead for photos and close it in crowded rooms. A transparent crossbody bag fits the theme, and the whole costume shrugs off rain.
32. Blue Butterfly Costume

For a blue butterfly, the wings decide whether you enjoy the night. I start with a fitted black jumpsuit, or a long-sleeve black top and leggings, and choose large blue patterned wings with soft flexible edges and padded shoulder straps; rigid wings jab people in a crowd and catch in doorways. Foldable wings are the safest bet for parties. Black ankle boots or blue ballet flats both work. Two space buns echo the antennae, with a light black antenna headband set behind them. Turquoise, navy and silver shadow blended out to the temples gives the wing effect around the eyes, and a few small face gems add dimension without full-face paint. Blue fingerless gloves and a sparkly waist belt tie the black base to the wings, and a tiny flower-shaped handbag suits the garden theme.
33. Blue Peacock Costume

Jewel tones carry a peacock, and the smartest decision here is the tail you don't build. Begin with a fitted cobalt jumpsuit, or a long-sleeve blue top and flowing teal skirt, and add peacock-print fabric panels at the back instead of a rigid oversized tail you'd have to steer through every room. Navy boots or metallic flats go beneath. A high braided blue ponytail with teal feather clips suits the look; keep any real feathers well away from the eyes and face. Emerald and sapphire shadow, dark liner, pearl highlighter and a small feathered design near one temple do the face. Gold earrings, a metallic belt and blue gloves add polish. A compact fan printed with feathers doubles as the prop, and the outfit stays easy to move in.
34. Blue Cloud Costume

A blue cloud is warm and gentle, a good pick for school or neighbourhood events. A sky-blue sweatshirt dress, or a matching sweater and leggings, makes the base. Attach small clusters of white craft batting at the shoulders and hem, kept away from your face; I hand-tack the batting with a few loose stitches, since glued batting flattens and drops off by the end of the evening. White tights and pale blue sneakers go underneath. Pastel-blue hair in loose curls or two fluffy buns with silver raindrop clips suits it. Blue liner, white shimmer, pink blush and tiny cloud shapes near the cheekbones keep the makeup airy. Carry a clear umbrella hung with felt raindrops, or swap to a cloud-shaped crossbody bag in crowds, and clip silver ribbon streamers on just for photos.
35. Blue Porcelain Doll Costume

A porcelain doll in blue stays sweet if you keep the makeup clean and skip the cracks. I'd find a powder-blue knee-length dress with puff sleeves, a white Peter Pan collar and a full skirt, and add white knee socks, blue Mary Janes and a small lace-trimmed bag. A medium-length blue wig in smooth curls or two low pigtails with satin bows suits her. The face is a matte base, round pink blush, carefully drawn lower lashes and a heart-shaped pink lip. I draw those lower lashes with a sharpened brown pencil rather than liquid liner, which smears the first time you laugh. White gloves and a blue headband finish the outfit. Practise a few posed movements for photos, but make sure the dress and shoes still let you walk normally. Pastel, navy and cobalt hair all suit it.
Matching Your Makeup to the Exact Blue
Blues split into two camps, and a costume looks more finished when the face sits in the same camp as the hair. Navy, cobalt and royal blue lean cool, so I pair them with silver, gray, cool pinks and berry lips. Turquoise, aqua and teal carry a little green, and they sit better next to gold, peach and coral. If you're unsure, hold the wig against your eyeshadow in daylight, not bathroom light, before you commit. Blue or gray face makeup also creeps into the wig hairline as you sweat, so I set the edge of my face with powder before the wig goes on.
Storing the Wig So It Survives Next Year
A blue wig is hard to replace in the exact same shade, so I look after it the night it comes off rather than the week after.
- Pick out face gems and glitter first, then comb with a wide-tooth comb from the ends upward.
- Wipe any makeup off the front of the cap, where blue or gray paint stains the fibres around it.
- Wash in cool water with a little gentle shampoo, rinse, and dry on a stand or tall bottle, never on a radiator.
- Store long wigs loosely braided inside a hairnet or bag so the ends don't knot.
- Keep twin tails, braids and beehives on a head form or stuffed with tissue so they hold their shape.
Short Bob or Long Waves Decides the Character
Blue hair turns an ordinary outfit into a character people can name from across the room, as long as the rest of the costume backs it up. If yours is a short cobalt bob, Coraline, Ramona Flowers and Sailor Mercury need almost nothing else. Long aqua hair belongs with mermaids, fairies, anime characters and space looks. Either way, I'd match the clothes, makeup, prop and shoes to the same shade family instead of letting the wig carry the night alone. Secure the wig, wear garments you can bend in, keep your eyes clear and choose shoes that suit the event. Then go with the character that feels most like you, famous or invented.
