A costume for four works when every person has their own part and the group still reads as one idea the second you walk in. That's the balance I look for in every quartet below: character crews, classic monsters, food jokes, colour-coded DIY themes and some very comfortable options for friends or families. The ones that land best right now have a clear theme and a shared colour story, while still letting each person stand out. For each look I've covered the clothes, hair, makeup, props and shoes, so you can split the list four ways. Buy matching pieces, raid a thrift shop, or pull from four wardrobes at once, and settle who's playing which role first.

Splitting Four Roles Without a Fight
Most group costumes fall apart in the planning, not on the night. Someone wants the starring role, someone else hasn't started a week before, and one person arrives in a shop-bought outfit while the other three made theirs. When I help a group of four, I settle a few things in the first conversation.
- Agree on effort and budget before the theme. A fully handmade group and a thrift-and-wear group need different ideas from this list.
- Pick a theme where the roles are roughly equal, or let the person who wants the big build take the hardest character.
- Choose one shared detail everyone wears, such as a colour, a fabric, a badge or the same shoes. It does more to connect a group than matching outfits.
- Make the shared pieces together. Emblems, labels and headpieces cut from one template come out the same size.
- Set a try-on date a few days before. Seeing all four together is the only way to catch a costume that's the wrong shade or reads as a different character.
Heights and builds matter too. Themes with flexible outfits, like seasons, elements or crayons, let each person choose a cut they're comfortable in, whereas character groups with fitted uniforms work best when everyone is happy wearing that shape.
1. Wizard Of Oz Group Costume

Dorothy, the Scarecrow, the Tin Man and the Cowardly Lion are about as balanced as a quartet gets, since nobody is the sidekick. Dorothy wears a blue gingham dress over a white blouse, braids, ankle socks and glittery red flats, with a small basket. The Scarecrow needs patched brown clothes, a floppy hat, straw-coloured yarn at the cuffs and comfortable boots. For the Tin Man, silver trousers, a metallic shirt, silver face makeup and a light funnel hat, with grey sneakers. The Lion takes a tan sweatsuit, a faux-fur mane, a brown nose and paw covers over sturdy shoes. I'd tell the Tin Man to paint last and set it hard with powder, because silver makeup is the one that ends up on everybody else in the photos.
2. Scooby-Doo Mystery Crew Costume

Fred, Daphne, Velma and Shaggy come almost entirely out of ordinary closets, which is why this crew is so popular. Fred wears blue trousers, a white sweater, an orange neck scarf and neat blond hair. Daphne needs a purple dress, a green scarf, red hair or a wig, lavender tights and low purple boots. Velma is an orange turtleneck, a red pleated skirt, knee socks, loafers, a short brown wig and round glasses. Shaggy takes a loose green T-shirt, brown trousers and messy hair. The scarves are what I'd check first: Fred's orange and Daphne's green have to be bright, saturated shades, or the group loses its cartoon colour. Flashlights, a notebook and a cardboard snack box are all the props you need.
3. Fantastic Four Superhero Costume

A shared blue-and-black uniform makes the Fantastic Four easy to photograph. Three of you, as Mister Fantastic, Invisible Woman and Human Torch, wear matching blue athletic tops, black leggings or trousers, black gloves and boots, with a handmade four emblem on the chest. When I make emblems for a group, I cut all of them from one template on the same day, because hand-drawn versions always come out slightly different sizes. Give Mister Fantastic grey-streaked temples and Invisible Woman loose blond waves; Human Torch gets flame-coloured eye makeup and temporary orange hair spray. The Thing wears an orange padded top, brown trousers, orange gloves and clean geometric face lines instead of a bulky mask. Strong poses, flexible sneakers, no combat props.
4. Teenage Mutant Ninja Turtles Group Costume

Four turtles means four equal roles and plenty of DIY. Dress everyone in green shirts, joggers, gloves and sneakers, then add lightweight brown foam shells and tan felt chest panels. Each person gets their own eye mask colour: blue, purple, red and orange. Green face makeup can stay on the cheeks and forehead for comfort, and temporary green hair spray is a fun extra. Wristbands, knee wraps and belts can all be torn from fabric strips. I'd make the four shells together as an assembly line, with one person cutting, one painting and one strapping, because it's quicker and they come out matching. Pizza boxes or foam slices replace the weapons, and sneakers keep you comfortable for walking and dancing.
5. Ghostbusters Group Costume

Ghostbusters is a uniform costume, which makes it one of the simplest to coordinate. Everyone wears a beige or khaki coverall, a black belt, elbow pads and sturdy black boots, with their own name patch so each person still has an identity. Hair stays natural or pulled back. A touch of grey shadow or a smudge of soot makeup suggests a long night on the job. The proton packs are painted cardboard boxes, flexible tubing and empty plastic bottles; I'd keep them under shoulder width and strap them high on the back, since a low pack swings and hits whoever is behind you. Gloves, safety goggles and printed ghost-detector cards finish it. This group wins the entrance, so walk in together.
6. Super Mario Group Costume

Mario, Luigi, Princess Peach and Toad give you four very different outlines in one bright theme. Mario wears blue overalls, a red shirt, white gloves, brown shoes and a red cap, with a brown mustache; Luigi copies the formula in green. Peach needs a long pink dress, blond waves, a small crown, soft pink makeup, white gloves and pink flats. Toad wears white trousers, a blue vest, brown shoes and a mushroom cap from foam or felt. Plush stars, gold cardboard coins or a question-block box make good props. I'd shorten Peach's skirt to ankle length before the night, because a floor-length dress in a group of four ends up stood on. Soft, removable mustaches are kinder too.
7. Toy Story Group Costume

Woody, Buzz, Jessie and Bo Peep share a theme but look completely different. Woody wears jeans, a yellow checked shirt, a cow-print vest, a red neckerchief, brown boots and a cowboy hat. Buzz needs a white athletic base with green and purple foam panels, a fitted hood and white sneakers. Jessie pairs jeans with a white western shirt, yellow details, a red hat, a red braid and boots. Bo Peep wears pale blue trousers or a knee dress, a pink cape, blond curls and blue flats. Buzz is the hardest build, so I'd hand him to whoever is happiest with a glue gun and give him a week. Rosy, cartoonish makeup on everyone, and a plush sheep or cardboard star for props.
8. Inside Out Emotions Group Costume

Joy, Sadness, Anger and Disgust are colour-coded, so even simple clothing reads clearly. Joy wears a yellow dress, a blue wig, bright eye makeup and flats. Sadness takes a pale blue sweater, navy trousers, a short blue wig, round glasses and sneakers. Anger is a white shirt, red tie, brown trousers, red face makeup and a felt flame headpiece. Disgust wears a green dress, a purple neck scarf, a green wig and long lashes. A clear plastic ornament makes a nice memory-orb prop for each. The thing I'd watch is red face makeup on Anger: it stains a white shirt collar fast, so set it with powder and dress before you paint. Big facial expressions make the photos, and soft knits keep everyone comfortable.
9. Alice In Wonderland Group Costume

Alice, the Mad Hatter, the Queen of Hearts and the White Rabbit give you a storybook group full of contrast. Alice wears a blue dress, white apron, black headband, blond hair, striped tights and black flats. The Hatter layers a colourful jacket, vest, bow tie, patterned trousers, a tall hat and a curly wig. The Queen needs a red-and-black dress, heart-shaped lip makeup, a small crown and comfortable boots. The Rabbit is all white with a red vest, ears, a pink nose and sneakers. A teacup, a cardboard clock, painted roses and oversized playing cards fill in the theme. The Hatter's tall hat is the one that falls off, so I add an elastic strap under the hair at the back. Keep every prop light enough to hold all night.
10. The Incredibles Family Costume

A red superhero family is quick to coordinate and easy to move in. Assign Mr. Incredible, Elastigirl, Violet and Dash, and fit each costume to the wearer. Everyone needs a red top with leggings or trousers, black gloves, a black eye mask, black briefs or shorts over the base, and tall black socks or boot covers. Add identical emblems from printable fabric transfer or layered felt. The reds are what I check most carefully: four red tops bought separately rarely match, so buy them together or dye them in one batch. Mr. Incredible wears neat blond hair, Elastigirl a short auburn wig, Violet long dark hair and Dash brushed-back blond. Subtle makeup under the masks, and black sneakers rather than stiff boots.
11. Golden Girls Group Costume

Dorothy, Blanche, Rose and Sophia are a quartet built on personality. Dorothy wears a long cardigan, a patterned blouse, straight trousers, sensible flats and a short grey wig. Blanche needs a bright draped dress, statement earrings, styled brown hair and low heels. Rose works in a pastel sweater, a midi skirt, pearls, a blond wig and loafers. Sophia takes a printed house dress, a cardigan, glasses, a white wig and chunky sneakers. I'd keep the age makeup light, just soft powder, rosy cheeks and a few drawn expression lines, because heavy ageing effects crack and look grubby after a couple of hours. A handbag, a recipe card, a newspaper or a little cheesecake box gives each of you a prop and a bit of comedy.
12. Mean Girls Pink Group Costume

Four pink outfits make the Mean Girls clique simple, and the details tell the characters apart. Assign Cady, Regina, Gretchen and Karen, and use mini skirts, fitted cardigans and camisoles as the base. Cady wears red or long auburn hair with a pink polo and jeans. Regina needs smooth blond hair, a pink cardigan, a black skirt and a small handbag. Gretchen picks dark curls, a fitted pink top, a plaid skirt and hoop earrings. Karen wears long blond hair, a pale pink top, a short skirt and a headband. When I style an all-pink group, I put each person in a different pink, one hot, one pale, one dusty and one bright, so you don't look like a team kit. Glossy makeup, flats, and a few notebooks or club flyers.
13. Clueless Fashion Group Costume

Cher, Dionne, Tai and Amber are a bright nineties school group, and plaid ties them together. Cher wears a yellow plaid blazer and skirt, white knee socks, blond hair and black Mary Janes. Dionne needs a black-and-white plaid outfit, a bold hat, long braids and platforms. Tai wears a graphic tee under an oversized cardigan with a plaid skirt, auburn waves and sneakers. Amber finishes the group in a red plaid skirt suit and loafers. Plaid suits are hard to find in the right colours, so I'd look for separates rather than sets: a blazer from one rail and a skirt from another often matches better than you'd expect. Fresh makeup with brown liner and lip gloss, plus mini backpacks or flip phones.
14. Stranger Things Group Costume

Eleven, Dustin, Lucas and Max are about the most thrift-friendly quartet there is. Eleven wears a pink dress, a blue jacket, striped socks, a short brown wig and white sneakers. Dustin takes a graphic T-shirt, a retro jacket, jeans, curly hair and a colourful cap. Lucas pairs a patterned shirt with a utility jacket, a headband, jeans and high-tops. Max wears a striped tee, a bright windbreaker, red hair and skate shoes. Flashlights, walkie-talkies, backpacks and arcade tokens make light props. This is one of the best groups for a cold walk, because I can tuck a thermal shirt or leggings under every one of those outfits without changing the shape.
15. Beetlejuice Group Costume

Beetlejuice, Lydia, Delia and Barbara make a theatrical group with no gore at all. Beetlejuice wears a black-and-white striped suit, a white shirt, messy green-tinted hair, pale makeup and black boots. Lydia picks a red layered dress, a dark spiky wig, soft smoky makeup and ankle boots. Delia needs an arty black outfit with sculptural red accessories, short styled hair and pointed flats. Barbara wears a floral midi dress, a cardigan, curled brown hair and low heels. The striped suit is the piece I'd sort first, since vertical stripes have to line up at the jacket front or the whole thing looks off. Keep his pale makeup light. A camera, a miniature house, an art portfolio and a striped guidebook make the props.
16. Addams Family Group Costume

Morticia, Gomez, Wednesday and Pugsley are an easy black-and-white family. Morticia wears a long fitted black dress, a straight black wig, red lipstick, dark eye makeup and low heels. Gomez needs a pinstripe suit, a white shirt, a bow tie, neatly parted dark hair and a thin mustache. Wednesday takes a black dress with a white collar, braided pigtails, black tights, pale makeup and Mary Janes. Pugsley completes the family in a black-and-white striped shirt, dark shorts, knee socks and sturdy shoes. With only two colours, texture does a lot of work, so I put velvet on Morticia and crisp cotton on Wednesday so they don't blur together. A black rose, a picture frame and a toy spider are safe props, and straight faces make the photos.
17. Classic Monster Group Costume

A vampire, a mummy, a werewolf and a stitched monster make the classic Halloween four. The vampire wears black trousers, a white shirt, a red-lined cape, slick hair, pale makeup and dress shoes. The mummy is cream clothing wrapped loosely in fabric strips, beige makeup and matching sneakers. I tear the strips from an old cotton sheet and tack them at the shoulders and hips, because wraps that are only tucked in start unravelling on the first flight of stairs. The werewolf wears a brown flannel shirt, dark trousers, faux-fur cuffs, tousled hair and brown face shading. The stitched monster takes a black jacket, green face makeup, drawn stitches and flat-top hair. Keep it stylised, and lanterns or old books tie the four together.
18. Hocus Pocus Witches And Cat Costume

The three Sanderson sisters plus a black cat give you four roles that work together. Winifred wears a green velvet-style dress, a red cape, a tall red wig, bold lipstick and black boots. Sarah needs a purple-and-red layered dress, long blond waves, shimmery eye makeup and heeled ankle boots. Mary wears a rust plaid dress, a dark cape, a high twisted updo and practical boots. The fourth person is the cat in a fitted black top and trousers, with ears, a tail and whiskers. Winifred's wig is the one to fuss over: a tall red style needs a wig cap and pins at the crown, or it slides back as soon as she laughs. A spellbook, a broom and a potion bottle of coloured water keep it playful.
19. Four Seasons Group Costume

Spring, summer, fall and winter suit a group of very different body types, because each person just picks comfortable clothes in their season's colours. Spring wears a green dress, a flower crown, pastel makeup and floral flats. Summer takes a yellow sundress, a sun headband, bronzed makeup and sunglasses. Fall combines a rust sweater with a brown tulle skirt, a leaf crown and ankle boots. Winter wears a white or icy blue dress, a faux-fur cape, silver makeup and a snowflake headpiece. Each person can carry a seasonal wreath. I'd agree on one shared length, all midi or all knee, because matching hems are what make four separate colour stories look like one group.
20. Four Elements Group Costume

Earth, air, fire and water turn colour into character without anyone needing to be famous. Earth wears a brown-and-green dress or jumpsuit, a leaf crown, braids and brown boots. Air picks flowing white layers, a silver headband, light curls and pale blue shadow. Fire needs a red, orange and yellow outfit, flame-shaped hair clips and warm makeup. Water wears a blue dress or set, wavy blue hair extensions and shimmery makeup. Give everyone a light fabric streamer or a clear orb in their colour. Fire is the one I'd style with the most care, since three bright colours together can look messy; I put the darkest red at the hem and the yellow at the shoulders so it reads as a flame. Similar fabrics hold the group together.
21. Crayon Box Group Costume

Four giant crayons make a DIY group with real impact from across a room. Assign red, blue, yellow and green, and dress each person in a matching shirt, trousers or leggings, socks and sneakers. The tunics are cylinders of poster board, felt or coloured foam, cut with generous armholes. Cone hats copy the crayon tip and stay on with soft elastic. Match hair to the colour with wigs, temporary spray or headbands, and add a colourful liner and a stripe on each cheek. Print one big label per tunic so the group reads clearly. I always make the cylinders from one flat pattern so all four are the same height and width, which matters more than anything else when you line up like a box of crayons.
22. Candy-Coated Chocolate Group Costume

Candy-coated chocolates are one of the most comfortable group costumes I know: red, yellow, green and blue sweatshirts, joggers or leggings, gloves and sneakers. Put a large white letter on each top, or a plain round candy symbol for a brand-free version. I cut the letters from white felt and stitch around the edge, because fabric glue on a fleecy sweatshirt goes stiff and peels after an hour. Matching beanies, bob wigs or hair spray, plus bright liner and glossy lips, keep it cheerful. White gloves and white shoe accents tie the four together. Each of you can carry a clear bag of tissue-paper candies. Round foam shoulder panels are optional, but keep them narrow enough for doorways.
23. Weather Forecast Group Costume

Sunshine, rain, clouds and a rainbow make a full forecast with four completely different outfits. Sunshine wears a yellow dress or set, a gold sun-ray headpiece, glowing makeup and yellow shoes. Rain takes a blue raincoat with blue trousers, raindrop face gems, a blue wig and waterproof boots. The cloud wears soft grey clothes, a headband covered in cotton wool, silver eye makeup and grey sneakers. The rainbow needs a striped dress, bright ribbons and multicoloured shoes. A cardboard weather map, a mini umbrella and a clear bag of white balloon clouds make the props. Cotton wool sheds over everything, so I'd glue it to the headband in one stuck-down layer and fluff only the top. Bright fabrics, no storm effects.
24. Condiment Bottle Group Costume

Ketchup, mustard, relish and hot sauce turn the fridge door into a four-person joke. Ketchup wears red with a pointed red cap and red sneakers. Mustard follows in a yellow sweatshirt and trousers, a yellow hat and gold liner. Relish needs a green outfit and a textured green headpiece. Hot sauce takes orange-red clothing, a flame-shaped cap and black shoes. Bottle labels cut from white felt go on each shirt, and foam cone hats copy the squeeze tops without bulk. I'd write the labels in the same lettering for all four, which is the detail that makes them look like a set rather than four separate costumes. A cardboard basket of felt fries or hot dogs makes the connection obvious.
25. Breakfast Food Group Costume

A waffle, a fried egg, a strip of bacon and a syrup bottle make a breakfast quartet that gets a laugh. The waffle wears tan clothing with a square felt grid tunic and a butter-pat hat. The egg needs white clothing, a round white tunic with a yellow centre and white shoes. Bacon layers a wavy red-and-cream striped foam panel over dark clothing and adds a wavy headband. The syrup bottle uses brown clothing, a printed label and a brown cap. Cardboard plates, forks or a menu make light props. Keep every tunic short enough to take a full step in. I put the shoulder straps a little inward on each panel so it hangs centred, since a tunic that drifts to one side ruins the line-up photo.
26. Rock Paper Scissors Referee Costume

Rock, paper and scissors need a fourth, and the referee is the clever part. Rock wears grey clothing, a light crumpled-foam shell, grey face shading and messy hair. Paper dresses all in white with ruled lines, a folded-paper headband and white shoes. Scissors wears silver with a cardboard scissor front panel, metallic shadow and slick hair, and I'd round every blade tip and wrap the edges in tape so nothing catches. The referee wears a black-and-white striped shirt, black trousers, a whistle, a cap and trainers, holding scorecards. The fun of this group is acting out rounds for photos, so it needs almost no character acting or expensive pieces.
27. Traffic Light And Crossing Guard Costume

Three traffic lights and a crossing guard make a street-safety group that's very easy to build. The red, yellow and green lights each wear black tops and trousers with one large felt circle on the chest, plus matching wigs or beanies, colourful eye makeup, black gloves and sneakers. Alternatively, each light can wear its colour head to toe under a black cardboard frame. The crossing guard needs a neon safety vest, navy trousers, a cap, a whistle and good walking shoes, with a foam-board stop sign. Reflective tape helps for real and suits the theme. When this group lines up for photos, I put red on the left, then yellow, then green, so the order reads like a signal.
28. Barbershop Quartet Costume

A barbershop quartet is made for exactly four, and it's polished with very little effort. Everyone wears a striped or white button-down shirt, a coloured vest, black trousers, a bow tie and black shoes, with a different vest colour for each singer. Straw boater hats, neat hair, curled mustaches and a touch of powder finish the look. Sheet music, a cardboard microphone or matching songbooks are the props, and white gloves make synchronised poses more theatrical. Boaters are stiff and slip off, so I add a thin elastic loop at the back that tucks under the hair. A made-up group name on each hatband is a fun touch. Most pieces are ordinary clothes, so it stays comfortable all evening.
29. Disco Dance Group Costume

Four disco dancers connect through shine rather than a uniform. One wears a silver jumpsuit, another a gold flared suit, the third a purple sequin dress and the fourth a blue satin shirt with bell-bottoms. Add stable platform shoes, oversized sunglasses, hoops and glittery headbands. Big curls, feathered layers, afros or sleek centre parts. Shimmery shadow and reflective cheek highlight finish the makeup. Vinyl record props or a mirrored-ball purse are fun extras. Sequins are scratchy under the arms, so I'd tell whoever wears the sequin dress to put a thin camisole underneath if it's unlined. Put one metallic accessory on every person and the group holds together on the dance floor.
30. 1980s Workout Group Costume

Neon workout gear is cheap, comfortable and full of energy. Give each person a different colour pairing, such as pink with purple, green with blue, orange with yellow, or turquoise with red. Layer leotards or fitted tanks over leggings, then add leg warmers, sweatbands, scrunched socks and supportive sneakers. Side ponytails, teased curls, mullets or fluffy wigs suit the decade. Bright blush, colourful shadow and glossy lips finish the face. Foam dumbbells or cardboard cassette players are easy props. I'd pick one neon shade that appears on all four, a sweatband or socks, so the group looks connected. Everything stretches, which makes this one good for dancing and long parties.
31. Western Rodeo Group Costume

A sheriff, a rodeo rider, a saloon singer and a ranch hand make a varied western group. The sheriff wears a tan shirt, dark jeans, a vest, a badge, a cowboy hat and boots, and carries a rolled town map instead of a weapon. The rider needs a checked shirt, denim, a fringed vest, a bandana and curled hair. The singer picks a ruffled midi dress, a fitted jacket, a hair accessory and low-heeled boots. The ranch hand wears overalls, a plaid shirt, a rope belt, a straw hat and freckles. Red bandanas and brown leather-look accessories repeat across all four. I'd make sure everyone breaks in their boots beforehand, because new western boots rub badly on a long evening.
32. Space Adventure Group Costume

An astronaut, an alien, the moon and a star make a bright space group with plenty of DIY options. The astronaut wears a white jumpsuit, silver patches, a clear helmet-style headband and white boots. The alien picks a green metallic outfit, an antenna headband, green face accents and silver sneakers. The moon needs a silver or pale grey dress, a crescent headpiece and shimmery makeup. The star wears a gold outfit, a star-ray crown and glittery shadow. A cardboard rocket, a planet orb and a mission clipboard make props. I'd cut the moon and star headpieces from foam rather than card, since card bends when it's knocked. Reflective fabrics catch the light, and keep faces uncovered.
33. Garden Friends Group Costume

A gardener, a sunflower, a bee and a butterfly make a cheerful group for friends or a family. The gardener wears denim overalls, a plaid shirt, a sun hat, gardening gloves and rain boots, with an empty watering can. The sunflower needs a green dress or jumpsuit, a yellow petal headpiece and green flats. The bee wears a yellow-and-black striped top, black trousers, soft wings and antennae. The butterfly picks a colourful dress, light wings and curled hair. Petal headpieces flop if the petals are felt alone, so I back each one with a strip of craft foam. Repeat yellow or green across all four. Skip real plants and soil, which get everywhere indoors.
34. Circus Performer Group Costume

A ringmaster, a clown, a strongman and an acrobat make a classic circus group with friendly makeup. The ringmaster wears a red tailcoat, black trousers, a white shirt, a mini top hat, gold eye makeup and tall black boots. The clown picks colourful overalls, a striped shirt, a bright wig, rosy cheeks, a red nose and big sneakers. The strongman needs a striped athletic top, black trousers, a curled mustache and wrist cuffs, with a foam barbell. The acrobat wears a sparkly unitard with a short wrap skirt, a sleek bun and dance shoes. Unitards are unforgiving to wear for hours, so I'd suggest one with a little thickness and a skirt over it. Red-and-gold accents and small ticket signs tie it together.
35. School Supplies Group Costume

A pencil, an eraser, a notebook and a ruler make a smart last-minute group from basic craft supplies. The pencil wears yellow with a pointed foam hat and a pink collar. The eraser needs a pink outfit, a rectangular felt tunic and a pink wig or beanie. The notebook wears white under a poster-board cover with blue lines and a red margin. The ruler wears tan clothing with measurement markings and a flat headband. Shoulder straps keep each panel in place, and oversized crayons or small backpacks are shared accessories. Poster board has sharp corners, so I round every one with scissors before anything else. Narrow panels let all four sit down, get through doors and pose side by side.
Standing in the Right Order for Photos
A group of four is judged mostly in photos, and the order you stand in changes how quickly the idea reads. Some themes have a natural order: red, yellow, green for traffic lights, spring through winter for the seasons, the crayons in a straight row like a box. Character groups read best with the most recognisable person in the middle.
- Stand close enough that shoulders nearly touch. A gap between people makes four costumes look like four strangers.
- Put props at chest height and keep them in front of the body, not hanging at your side.
- Face light, not a window behind you, so face makeup and colours show.
- Take one shot with everyone posing in character and one relaxed; the in-character one is usually the keeper.
When One Person Drops Out
It happens most years: someone gets sick or a babysitter cancels. Some themes survive as a trio and some don't. Crayons, candy, condiments, disco dancers and workout gear still work with three, because each person is a variation on one idea. Seasons, elements, the Fantastic Four and rock, paper, scissors with a referee look incomplete. If your group has a shaky fourth member, I'd pick a theme from the first set.
Four People, One Clear Idea
The best way to pick from these is to agree on comfort, budget and effort before anyone shops. Character quartets give each person a defined role, while crayons, weather, food and seasonal themes leave more room to personalise. Assign roles early so two people don't turn up as the same character. Then repeat a colour, a fabric, a label or an accessory across all four, which is what makes a group look planned. Light props and supportive shoes will make the night far more fun. Nostalgic characters, classic monsters, silly DIY food or bright colour-matched sets all work, as long as the four-part idea is clear enough to read in one photo.
