A blonde and a brunette standing side by side already look like a pair, which takes a lot of pressure off the costume. What turns two outfits into two characters is the signature piece each one owns: the headband, the plaid, the cape, the hat. Below are 35 pairs, from best friends and movie rivals to princesses, superheroes, a couple of male duos and some original ideas like a sun and moon. Most can be built from closet basics, thrift finds and cheap craft supplies. I've noted where I'd swap heels for flats or foam for cardboard, because the pair that's still comfortable at eleven at night is the one that ends up in the good photos.

If It's Raining or Freezing on Halloween Night
A lot of these pairs are short skirts, thin satin and bare shoulders, and late October doesn't always cooperate. I'd plan the warm layer before the costume rather than throwing a puffer over it at the door, which hides everything you worked on.
- Thermal leggings or opaque tights in the costume's colour go under almost every skirt here, and nobody notices them in photos.
- A thin long-sleeve base layer in nude or black disappears under sleeveless dresses, superhero tops and cheer sweaters.
- Pick a coat that belongs to the character where you can: Buffy's jacket, a velvet cape for a witch, a robe for Draco, a cloak for Aragorn. Then the warm layer is part of the costume.
- Cardstock crowns, paper spectacles and cardboard props go soft and limp in rain. Spray them with a clear sealer the day before, or bring a spare.
- Hot glue gets brittle in the cold and lets go, so anything that must stay on outdoors is better stitched or held with contact cement.
Shoes matter more than people expect on a wet night. Ballet flats and satin pumps soak through in minutes, so if you're walking any distance, I'd wear boots and carry the costume shoes for photos.
1. Serena And Blair Costume

Serena is the undone one and Blair is the buttoned-up one, so dress them in the same school pieces and let the attitude split them. Serena gets a white button-down loosely tucked into a plaid skirt, a relaxed tie, tall boots and a slouchy shoulder bag, with loose waves and soft bronze makeup. Blair wears a fitted blouse, a pleated skirt, opaque tights, polished loafers and a structured bag, with smooth waves, a velvet headband and rosy lipstick. A notebook or an invitation is plenty for props. I'd put most of the budget into Blair's headband, because it's the single piece people use to name her.
2. Regina And Gretchen Costume

Pink holds this pair together, so I'd pick two different pinks rather than two identical tops. Regina wears a pink cardigan over a white fitted tank with a plaid mini and simple pumps or ballet flats, smooth blonde hair, glossy lips and a small handbag. Gretchen wears a pink sweater, a plaid skirt, sheer tights and loafers, with voluminous soft curls, pink blush and gloss. Handmade notebooks and flip phones are fun props. Short plaid skirts ride up when you sit, so a pair with built-in shorts, or bike shorts underneath, makes the night much easier.
3. Glinda And Dorothy Costume

Glinda and Dorothy read from across a room because pink, blue and red never get confused. Glinda wears a pale pink full-length dress or a layered tulle midi, silver ballet flats, a sparkly crown and a light star wand, with soft curls and shimmery pink makeup. Dorothy wears a blue gingham dress over a white puff-sleeve blouse, ankle socks and bright red flats, with two braids tied in blue ribbon and a small basket holding a stuffed dog. I'd choose soft cotton gingham over the stiff costume-shop version; it hangs like a real dress and doesn't crackle when you move. If the red flats are plain, red glitter heat-transfer vinyl on the toe caps lasts far longer than loose glitter and glue.
4. Elle Woods And Vivian Kensington Costume

Elle's pink against Vivian's navy is the whole joke, and it only lands if Vivian stays plain. The blonde wears a fitted pink blazer, a matching skirt, a white top and pink heels or flats, with straight, smooth hair, rosy makeup, glossy lips and a small pink bag. Give her a law book and a stuffed toy dog. The brunette wears a navy blazer, tailored trousers or a knee-length skirt, loafers and a structured tote, with sleek hair parted to the side and refined makeup. A folder labelled with a made-up class name is a nice touch. Both outfits are real clothes, which is why this pair stays comfortable through a long party.
5. Barbie And Raquelle Costume

Barbie and Raquelle are friendly rivals, so I give them the same silhouette and opposite colours. Barbie wears a bright pink fit-and-flare dress, a cropped jacket, pink pumps and big sunglasses, with a high ponytail or polished waves and pink lipstick. Raquelle wears a purple mini dress or a matching top and skirt, black tights, heeled ankle boots and a metallic bag, with sleek voluminous hair and plum-toned eyes. Keep the props doll-sized: toy handbags and costume jewellery. A high ponytail looks fuller if you tease a little at the base before tying it and wrap a strand around the band to hide the elastic.
6. Lizzie McGuire And Isabella Costume

Lizzie and Isabella are a pop-star pair, and it's easy to overdo it, so I keep one colour story per person. Lizzie wears a sparkly blue crop top over a fitted camisole, flared pants, platform sneakers and a light headset mic, with crimped sections or a playful half-up style, blue shimmer and gloss. Isabella wears a metallic green or gold top with a matching skirt or flares, platforms and bold costume jewellery, with long straight hair and gold accents on the eyes. They should look like they're on the same stage without matching. Toy microphones give you both a pose for every photo.
7. Sharpay And Gabriella Costume

Sharpay sparkles and Gabriella dresses like a student, and that difference has to stay obvious. Sharpay wears a sequined pink top, a coordinating skirt, a cropped cardigan and glittery ballet flats, with polished curls, a rhinestone headband, bright pink lipstick and a star-shaped bag. Gabriella wears a red school-style top, a dark skirt or jeans, white sneakers and a simple pendant, with soft natural waves and fresh makeup. Sheet music or toy mics connect them. Sequins scratch the inside of the arms after a few hours, so if the top has long sleeves, I'd wear a thin long-sleeve tee underneath.
8. Cher And Dionne Costume

This is all about the plaid, and the two plaids must look clearly different side by side. Cher wears a yellow plaid blazer and matching skirt over a white top with knee-high socks and black Mary Janes, long straight hair, neutral makeup and a tiny backpack. Dionne wears a black-and-white plaid blazer and skirt, a bright blouse, sheer tights and platforms, with her hair under an oversized hat, polished lipstick and statement earrings. Flip phones and fuzzy pens are easy props. I keep the focus on the pattern and the accessories, and never on changing anyone's skin tone; the clothes say everything.
9. Phoebe And Rachel Costume

Phoebe and Rachel come straight out of an ordinary wardrobe, which makes them a good last-minute choice. Phoebe layers a colourful printed maxi dress over a fitted top with ankle boots, long necklaces and a toy acoustic guitar, plus loose waves or tiny braids around the face and natural makeup. Rachel wears a green café apron over a black fitted top and denim skirt, opaque tights and loafers, with a smooth layered blowout and soft brown makeup. A coffee mug and order pad tell people where she works. The layered blowout is the hard part; a round brush and a few big rollers while you do your makeup will get you most of the way.
10. Sandy And Rizzo Costume

Sandy and Rizzo are the end-of-film versions, and the black off-the-shoulder top is what people recognise. Sandy wears it with high-waisted fitted pants, a wide belt and red slip-on heels, with bouncy curls, red lipstick and winged liner. Rizzo wears a pink satin jacket over a black blouse, cropped pants or a pencil skirt and black pumps, with short vintage curls or a temporary brunette bob wig, cat-eye makeup and deep rose lipstick. Vintage sunglasses or a retro bag are easy props. Real leather-look pants are hot and stiff, so I'd choose a stretch coated legging and low heels if you plan to dance.
11. Betty And Veronica Costume

This Betty and Veronica is the small-town version, not the cheerleaders, and it's mostly about how polished each girl looks. Betty wears a pastel sweater over a collared shirt, an A-line skirt, ankle socks and loafers, with a neat ponytail, fresh makeup and pink blush, carrying a notebook or a school newspaper. Veronica wears a fitted dark dress, a pearl necklace, a structured coat and polished ankle boots, with glossy smooth waves and a classic berry lip. A small handbag is all she needs. If the pearls are plastic, I'd buy a strand with a little weight; very light ones bounce and twist in photos.
12. Buffy And Faith Costume

Buffy and Faith don't need weapons or blood to read, just the red jacket against the black one. Buffy wears a fitted red leather-look jacket, a black tank, dark pants and sturdy ankle boots, with loose waves and clean makeup. Faith wears a black moto jacket, a dark fitted top, cargo pants and lace-up boots, with loose tousled hair, wearable smoky eyes, hoop earrings and fingerless gloves. A school notebook or a crossbody bag stands in for a stake. I like this pair for a crowded party, because the pants and boots let you move and nothing on either costume catches on anyone.
13. Caroline And Bonnie Costume

Caroline and Bonnie hint at the supernatural through mood rather than makeup. Caroline wears a fitted jewel-tone dress, a cropped jacket, heeled ankle boots and a delicate pendant, with polished curls, luminous skin and berry lipstick. Bonnie wears a dark green blouse, black jeans or a flowing midi skirt, ankle boots and layered necklaces, with naturally textured or softly waved hair and warm neutral makeup. An old journal and a battery candle are good atmosphere. I'd use battery candles only, never real flame, near flowing sleeves and loose hair. Don't change anyone's skin tone; the wardrobe and hair carry the characters.
14. Cassie And Maddy Costume

Cassie and Maddy are two party looks with a lot of beauty detail, so plan the makeup before the clothes. Cassie wears a pale blue fitted top with a cow-print skirt, white ankle boots and a small shoulder bag, with soft curls, blue shimmer and glossy lips. Maddy wears a black halter top with high-waisted cutout pants, strappy heels and silver hoops, with a sleek ponytail or straight hair, graphic liner and rhinestone accents. If you're going somewhere public, a nude bodysuit under the halter and cutouts keeps everything in place. Graphic liner goes on cleaner with tape as a guide, but I'd test the tape on the back of your hand first.
15. Jules And Rue Costume

Jules and Rue are a casual pair, and the gap between bright and understated is the point. Jules wears a pastel mesh top over a camisole, a pleated skirt, patterned tights and chunky sneakers, with a blonde bob, colourful clips and soft pink-and-blue eyes. Rue wears an oversized burgundy hoodie, a graphic tee, relaxed cargo pants and worn-in sneakers, with natural curls or loosely tousled hair and minimal makeup. A small backpack and folded school papers are enough. Leave out any props tied to the show's adult storylines. Mesh tops snag on velcro and jewellery, so I'd take off chunky rings before you put it on.
16. Sabrina And Prudence Costume

Sabrina and Prudence suit a pair who want magic without anything frightening or ritual-looking. Sabrina wears a red long-sleeve dress with a white collar, black tights, Mary Janes and a matching headband, with a softly curled bob and classic red lipstick. Prudence wears a structured black dress with lace sleeves, opaque tights, heeled ankle boots and an elegant capelet, with a sleek centre part or long braids, plum lipstick and defined liner. Vintage-style books and battery candles are the props. The red and black read as Halloween straight away. A capelet sits better if you add a small hook and eye at the neck rather than relying on a ribbon tie, which slips.
17. Luna And Hermione Costume

Luna and Hermione wear the same uniform, so the accessories do the separating, and that suits almost any age. Luna wears a grey sweater over a collared shirt, a pleated skirt, a striped tie, knee socks and black lace-up shoes, with long waves, dangling quirky earrings and colourful paper spectacles. Hermione wears a darker cardigan, opaque tights and loafers, with soft brushed volume and natural makeup. Both get a vintage book and a smooth wooden wand with a rounded tip. For Hermione's volume, I'd brush out a braid that's been in overnight rather than backcomb. A warm scarf each helps on a cold October night.
18. Tinker Bell And Wendy Costume

Tinker Bell and Wendy are green against pale blue, and the wings are the only tricky piece. Tink wears a leaf-shaped green dress over matching shorts, translucent wings, green ballet flats and a small pom-pom in her hair, with a high bun and sparkly green eye makeup. Wendy wears a modest light blue dress with puff sleeves, white ankle socks and flats, with a low ponytail tied in a wide blue ribbon and soft rosy makeup. Tink carries a pouch of biodegradable paper confetti; Wendy holds a storybook. Wider wings knock into doorframes, so for a busy house party I'd choose a pair that stays inside the line of your shoulders.
19. Cinderella And Belle Costume

Cinderella and Belle each own a colour, so get the shades right and the rest is easy. Cinderella wears a pale blue full-skirted midi dress, a black ribbon choker, silver flats and a glittery headband, with a smooth high bun, a few loose strands at the face and icy blue shimmer. Belle wears a golden-yellow dress with a fitted bodice, gold flats and fine drop earrings, with loose curls half up and warm, natural makeup. A clear decorative slipper and a fabric rose are the props. I keep both skirts at ankle or midi length; a trailing hem gets stepped on, and full skirts snag on car doors.
20. Rapunzel And Mother Gothel Costume

Rapunzel and Mother Gothel give you a heroine and a villain without anything scary. Rapunzel wears a lavender lace-up dress with puff sleeves and flats, with small artificial flowers tucked into a long braid, soft purple eyes and a frying pan made from painted cardboard. Gothel wears a burgundy velvet-look gown with a wide belt, low black boots and a gold pendant, with long full curls, strong brows and deep berry lipstick. The braid is the showpiece; a cheap braided hair extension clipped under her own hair adds length, and I wire the flowers on with thin floral wire so they don't drop out. Keep both hems short enough to walk safely.
21. Princess Peach And Daisy Costume

Peach and Daisy are pink and yellow colour blocks, and that's what people recognise first. Peach wears a pink puff-sleeve dress, white gloves, pink flats and a light gold crown with faux gems, with smooth curls and rosy makeup. Daisy wears a yellow-and-orange dress, white gloves, orange flats and a floral crown, with a bouncy lob or a curled wig and warm peach makeup. Each can carry a plush star or a toy racing flag. Shorts under the dresses and flat shoes make this one fine for a campus event. A light crown stays put better on a thin headband than balanced on bobby pins.
22. Supergirl And Wonder Woman Costume

Supergirl and Wonder Woman share red and blue, so I flip which colour sits on top for each. Supergirl wears a blue long-sleeve top with a red knee-length skirt, a red cape, opaque tights and red ankle boots, with loose waves and red lipstick. Wonder Woman wears a red structured top, a blue skirt or leggings, gold wrist cuffs and red boots, with big polished waves, a gold headband and defined liner. Foam emblems and fabric accessories are lighter and safer than hard armour. Cut both capes to stop above the back of the knee, or someone will step on them on the stairs.
23. Black Canary And Zatanna Costume

Black Canary and Zatanna are both mostly black, and the hair colour is what keeps them from blending. Black Canary wears a black fitted jacket over a high-neck top, stretch faux-leather pants, patterned tights and combat boots, with loose waves and smoky eyes. Zatanna wears a black blazer with satin lapels, a white button-down, tailored shorts over opaque tights and heeled ankle boots, with a small top hat, white gloves, red lipstick and glossy waves. Playing cards or a collapsible wand make harmless props. In a dim room black on black disappears, so I'd make sure Zatanna's white shirt and gloves are crisp.
24. Harley Quinn And Catwoman Costume

Harley and Catwoman stay playful without any weapons, and the pigtails carry Harley. She wears a red-and-black bomber, matching shorts over opaque tights, high-tops and fingerless gloves, with two high pigtails tipped in temporary red and blue and colourful eye makeup. Catwoman wears a fitted black jumpsuit or a black top with stretch pants, ankle boots, a cropped jacket and a cat-ear headband, with a sleek ponytail and sharp winged liner. Big playing cards for Harley and a small belt bag for Catwoman keep hands free. Temporary hair colour on blonde ends can stain for a wash or two, so test a hidden strand first.
25. Cersei And Margaery Costume

Cersei and Margaery are both royal, but the colours tell you whose house is whose. Cersei wears a structured burgundy or black maxi dress, a gold belt, low boots and a small crown, with loose medieval waves or a braided half-up style, strong brows and a deep neutral lip. Margaery wears a blue or teal flowing dress with a fitted waist, fine gold jewellery and matching flats, with an intricate half-up style in soft curls and luminous skin. Decorative goblets of water or folded letters make good props. I'd stick to ankle-length dresses here; they still look regal and they're far safer on stairs.
26. Daenerys And Missandei Costume

Daenerys and Missandei are about drape and braids, and jersey is the fabric I'd reach for. Daenerys wears a pale grey wrap dress or a long tunic over fitted pants, flat boots and a soft cape, with several small braids through long blonde hair and cool, natural makeup. Missandei wears a teal or blue draped maxi, flat sandals or ankle boots and a simple metallic belt, with braids or her natural texture and understated gold makeup. Rolled parchment maps are safe props. Keep it to clothing, hair and accessories, never anyone's complexion. Jersey drapes like a much pricier fabric and you can sit, dance and drive in it.
27. Draco And Harry Costume

Draco and Harry are an easy pair for two men, two friends or siblings, and most of it is school uniform. Draco wears a white shirt, a green striped tie, a grey sweater, black trousers, polished shoes and a black robe, with short hair slicked to one side. Harry wears a white shirt, a red-and-gold striped tie, a dark cardigan, black pants, sneakers or loafers and the same robe, with tousled hair, round glasses and a small lightning mark drawn in eyeliner. Old books and rounded wands for both. House scarves are the quickest way to tell them apart, and they're welcome on a cold night.
28. Legolas And Aragorn Costume

Legolas and Aragorn are mostly thrifted layers, which is good news for anyone who doesn't sew. Legolas wears a forest-green tunic, fitted brown pants, soft knee-high boot covers, a light cape and pointed ears, with long blonde hair and small side braids. Aragorn wears a dark grey tunic, a brown vest, rugged trousers, black boots and a weathered cloak, with shoulder-length tousled hair and a little beard shading if he wants it. Maps, travel pouches and a leaf brooch stand in for weapons. Prosthetic ears hold better with spirit gum or a skin-safe adhesive than tape; patch-test it first, and take them off slowly with remover.
29. Thor And Loki Costume

Thor and Loki contrast silver against gold, and foam is what keeps the armour wearable. Thor wears a black fitted shirt with silver foam panels, dark pants, a red cape and black boots, with loose shoulder-length waves and a neat costume beard if he likes, plus a light grey foam hammer with rounded edges. Loki wears a long dark green coat, black trousers, gold foam shoulder pieces and black boots, with hair slicked back and some cheek contour. A soft gold headpiece finishes him without being huge. Hot glue on foam lets go in cold air, so if you're outdoors I'd glue the panels with contact cement or sew them to the shirt.
30. Johnny And Daniel Costume

Johnny and Daniel are a nostalgic pair you can put together in an afternoon. Johnny wears a black sleeveless martial-arts top over a fitted tee, a contrasting belt, white athletic shoes and a printed headband, with short hair given a little lift. Daniel wears a white uniform, a dark belt, white sneakers and a matching headband, with softly feathered hair. No fighting props needed; a felt tournament patch makes the theme clear. Felt patches glued onto cotton peel in the wash, so I'd stitch them on by hand with a few big stitches. The tee underneath helps if the party spills outside.
31. Blonde Angel And Brunette Devil Costume

An angel and a devil is the classic pair of opposites, and it stays family-friendly if you keep it cute. The angel wears a white midi dress or a white top with flowing trousers, silver ballet flats, feather-free fabric wings and a light halo, with soft curls and pearly makeup. The devil wears a fitted red dress or jumpsuit, black ankle boots, a red capelet and a simple horn headband, with sleek hair, red lipstick and subtle winged liner, carrying a red heart-shaped purse instead of a pitchfork. I match the dress lengths so the pair looks planned. Fabric wings are kinder than feathers, which shed on every chair you sit on.
32. Blonde Fairy And Brunette Witch Costume

A fairy and a witch is light against dark, and you can keep it whimsical rather than spooky. The fairy wears a pastel green layered dress, translucent wings, floral hair clips and lace-up ballet flats, with loose waves, iridescent pink-and-green makeup and a flower-topped wand. The witch wears a black or deep purple midi dress, striped tights, buckled ankle boots, a velvet cape and a wide-brim pointed hat, with glossy waves, plum eyes and a berry lip, plus a small broom or a spellbook. A wide hat brim flops by the end of the night; I'd look for one with wire in the edge, or run a line of millinery wire through it yourself.
33. Blonde Sun And Brunette Moon Costume

A sun and moon pair is your own invention, which means nobody can tell you it's wrong. The sun wears a metallic gold top with a flowing yellow skirt or wide-leg pants, gold sandals and a radiant cardstock crown, with big waves and warm gold shimmer. The moon wears a silver or midnight-blue jumpsuit, silver ankle boots, a crescent headband and star earrings, with sleek or soft curls and cool silver makeup. Small crossbody bags with sun and moon symbols keep hands free. I'd use pressed shimmer instead of loose glitter, which ends up in everyone's drinks, and make sure every star is glued or stitched down firmly.
34. Blonde Pop Star And Brunette Rock Star Costume

A pop star and a rock star let you make up your own characters instead of copying a celebrity. The pop star wears a silver sequined jacket over a bright bodysuit and high-waisted pants, white platform sneakers and a light headset mic, with a high ponytail and sparkly eye makeup. The rock star wears a black graphic tee, faux-leather pants, studded ankle boots and a red cropped jacket, with tousled waves, smoky liner and deep red lipstick, plus an inflatable guitar. I repeat one silver accessory on both, like matching chains, so they look like they're on the same bill.
35. Blonde And Brunette Disco Cowgirl Costume

Disco cowgirls are fringe and sparkle, and this pair is built to dance in. The blonde wears a silver fringed shirt with white flared pants, metallic ankle boots, a white cowboy hat and star earrings, with full curls and silver shimmer around the eyes. The brunette wears a gold or bronze fringed top, dark brown flares, gold boots and a matching hat, with soft waves, bronze makeup and glossy lips. Rhinestone belts and small metallic bags are plenty; skip toy guns and bulky props. Silver for the blonde and gold for the brunette echoes the hair. Fringe tangles in storage, so I hang the tops upside down after wearing.
Capes, Wings and Halos That Last Past Midnight
The add-on pieces are what fail first. A halo tips sideways, a cape strangles you every time you sit, wings slide down your back. Here's how I build them so they're still where they belong at the end of the night.
Capes
Fasten a cape at the shoulders, not just at the throat, so the weight sits on your body rather than your neck. Two small safety pins through the cape and the shoulder seams of your top on the inside do it. Hem it above the back of the knee for stairs and crowds, and use a light fabric; heavy velvet looks rich but drags.
Wings
Elastic straps on wings dig into the shoulders after an hour or two. I cover them with a soft fabric sleeve or a strip of felt, and add a third strap across the chest if the wings are wide. Keep the span inside your shoulders for indoor parties.
Halos, crowns and horns
Anything that stands up needs a firm base. I attach halos and horns to a plain headband with wire wrapped tightly and covered in tape, then slide two bobby pins through the band into the hair behind each ear. A crown sits steadier pinned into a small bun than balanced on loose hair.
Hair Is Half the Costume
The contrast between your hair colours gives every pair a head start, but the clothes, makeup and one good prop each are what make people say the names out loud. Pick characters you'll both enjoy playing, then decide how much effort you want: a thrifted closet version, everyday clothes with a twist, or a proper fantasy build. Let comfort make the final call. Walk around the house in your shoes, pin down capes and wings, and keep props light. If your natural colours don't fit the pair you love, a wig fixes it. From school uniforms and princesses to superheroes and a sun and moon of your own design, there's a pair here for best friends, couples, siblings and any two people who like dressing up together.
