Dressing six people is a project. Dressing twenty is a small production, and the theme decides how hard it gets. The groups below suit friend crews, families and office teams, and each one has clothes, hair, makeup, props and shoes written out. Some are built on named characters; others run on a colour or a simple shape, so a cousin who says yes on Friday can still join. Hand out roles early, agree on the one or two details everyone shares, and let each person put their own spin on the rest.
Running a Costume Plan for Ten or More People
With a big group, the costume is the easy part. The hard part is keeping everyone on the same page while they each shop on their own. A few rules I set at the start save a lot of messages later.
- Keep one shared list with every name, their role, their colour and what they still need. A simple shared spreadsheet or a pinned group message is enough.
- Choose two or three shared details and make them non-negotiable: a colour family, a shoe type or one accessory. Everything else is the wearer's choice.
- Give every theme a flexible role for late joiners, like card soldiers, army men, aliens or extra rainbow colours, so you never have to reshuffle the main characters.
- Set a cut-off date for buying, about a week before the event, so slow shippers don't leave someone half-dressed.
Budget is where groups quietly fall apart. If one person spends a lot and another can only thrift, the photos show it. I steer big groups toward themes built on clothes people already own, with one cheap handmade piece each, so nobody feels outdressed.
1. Crayon Box Group Costume
This is the theme I reach for when the head count keeps changing. Each person takes one colour and wears a tee, leggings or pants and sneakers in it, with a pointed hat rolled from cardstock and black paper bands near the top and bottom of the outfit. Roll the hats around a cone of newspaper first so they come out even, then tape them shut inside. A sweep of matching shadow or glitter is plenty of makeup. One person can be the box in a red-and-yellow cardboard tunic, and the rest stand in neat rows beside them.
2. Wizard School Group Costume
White button-downs, dark skirts or trousers, striped ties and black robes make the uniform, and scarves and sweater vests sort everyone into burgundy, green, blue or yellow houses. Keep hair and makeup natural with a little shimmer, and give each student a cardboard wand, an old book or a small plush owl. Black loafers, boots or flats finish it, and the teachers get longer robes and tall hats. Robes are the expensive part, so I tell big groups to check graduation gown resellers; a black gown with the yoke trimmed reads the same. Personal badges stop twenty students looking cloned.
3. Toy Story Character Group Costume
The films have enough characters that a mixed-age crowd rarely has to double up. Hand out Woody, Buzz, Jessie, Bo Peep, Barbie, Ken, Rex, Hamm, Slinky Dog and a handful of aliens, built from western shirts, cow-print vests, bright jumpsuits, pink dresses, dinosaur hoodies and lime tops. Match each character's hair with braids, hats, headbands or light wigs, and keep cardboard accessories small. Slinky Dog is the hard one; a brown hoodie with a dryer duct painted tan around the middle bends well and weighs almost nothing. Anyone who joins late becomes a green army soldier.
4. Mario Kart Racer Group Costume
Mario, Luigi, Peach, Daisy, Toad, Yoshi, Bowser, Wario and Waluigi each start from bright shirts, overalls, dresses, gloves and caps in their character colour. Add makeup mustaches, soft curls and light crowns for the princesses, and character headbands for the rest. The karts are cardboard boxes worn around the waist on shoulder straps, with painted wheels and big numbers. Cut the box a hand's width wider than the hips on each side or it rubs the thighs raw when you walk. Sneakers only, and give each racer a foam star, shell or flag.
5. Minions Group Costume
Minions scale to almost any size with very little prep. Most people need a yellow shirt or hoodie, denim overalls, black gloves and black sneakers, with goggles made from silver-painted cardboard rings on black elastic. A yellow beanie with a few black pipe cleaners poked through handles the hair; yellow face makeup is optional, since the clothes already do the work. Add Gru in a dark coat and striped scarf, Lucy in turquoise and Vector in an orange tracksuit. Thick cardboard goggles press on the nose bridge, so I glue a strip of felt along the inside edge.
6. Inside Out Emotions Group Costume
Each emotion has its own colour, so this one is easy to assign: Joy in a yellow dress, Sadness in a blue sweater and pants, Anger in a red shirt and tie, Disgust in green, and Fear, Anxiety, Envy, Embarrassment and Ennui after them. Match wigs or temporary hair colour to each one, with shadow and blush in the same shade. Memory orbs, emotion labels or control-panel buttons work as props. A clear plastic ornament ball with a little coloured tissue inside makes a light memory orb that glows under party lights. If you outnumber the film, invent emotions like Excitement or Calm.
7. Scooby-Doo Mystery Crew Costume
Pair the five mystery solvers with a crowd of masked villains and you get a whole scene. Fred wears a white sweater, blue pants, an orange neck scarf and a blond wig. Daphne has a purple dress, green scarf, lilac headband and boots; Velma an orange sweater, red skirt, glasses and knee socks; Shaggy a green shirt, brown pants and messy hair. One person goes as the dog with a blue collar. Everyone else becomes ghosts, mummies, robots and swamp creatures, and the villains should wear their masks on top of the head between photos so they can see.
8. Superhero Team Group Costume
Original heroes let everyone pick their own colour and power. Build each suit from a fitted long-sleeve top, leggings or joggers, a short cape, gloves and sturdy boots or sneakers, with a fabric emblem for lightning, stars, water or plants. Metallic shadow and graphic liner give a comic finish without covering the whole face. Use the same emblem shape and the same wrist cuffs on everybody, and twenty different heroes still look like one team. I cut every emblem from one template so the size matches, and keep capes at hip length so nobody gets stepped on.
9. Greek Gods Group Costume
A mythological court needs flowing fabric, gold and a few symbols. Tunics can be made from white sheets or jersey, belted in gold with a draped shoulder piece and flat sandals. Assign the sky, sea, wisdom, love, harvest, music and sun, and give each figure a crown of faux leaves, shells, stars, flowers or gold card. Jersey drapes better than sheeting because it doesn't fray, so you can leave the edges raw. Bronze shadow and soft highlighter suit everyone, and jewel-tone capes pick out the important gods.
10. Alice In Wonderland Group Costume
Wonderland gives big groups plenty of roles: Alice, the Mad Hatter, the Queen of Hearts, the White Rabbit, the Cheshire Cat, card soldiers and tea-party guests. Alice wears a blue dress, white apron, black headband and flats. The Hatter gets a bright coat, patterned trousers, a large hat and colourful curls; the Queen a red-and-black dress, heart crown, strong lipstick and boots. The Rabbit wears ears, a vest and a cardboard clock. Card soldiers are the cheapest place to put extra people; foam board tunics on ribbon shoulder straps hang flat and slip off fast when someone needs to sit.
11. Wizard Of Oz Group Costume
Dorothy wears blue gingham, braids, red shoes and carries a basket. The Scarecrow is patched brown clothing with straw-coloured trim, the Tin Man silver layers and the Lion a soft brown mane with a matching outfit. Glinda wears a pink gown and crown; the Witch a black dress, pointed hat, green makeup and boots. Everyone else can go as flying monkeys, Emerald City residents or Munchkins. Real straw sheds everywhere, so I use raffia instead, and the props stay cardboard: a heart, a diploma, a medal, lollipops and a tiny balloon.
12. Circus Performer Group Costume
A circus cast covers ringmasters, clowns, acrobats, strong performers, a fortune teller, ticket sellers and popcorn vendors, which means everyone picks their own comfort level. Ringmasters wear red jackets, black trousers, gold trim, top hats and boots. Acrobats layer bright leotards over opaque tights with sparkly jackets, and clowns stay cheerful with patterned overalls, suspenders, bow ties, bright wigs and painted cheeks instead of masks. Strong performers get striped tops and foam barbells, vendors aprons and snack trays. Gold braid trim from a fabric shop turns a plain red blazer into a ringmaster coat with a few stitches.
13. Glow-In-The-Dark Skeleton Group Costume
No one has to learn a character for a skeleton squad. Start with black long-sleeve tops and leggings, jumpsuits or sweatsuits, and add white or glow fabric bones. Lay the bones out while the person is wearing the shirt and pin them in place, because what lines up flat on a table drifts once arms bend. Paint white lines around the eyes, cheekbones and jaw, or use face stickers if you're short on time. Black shoes keep the silhouette clean. Let each skeleton add a bow tie, tutu or top hat, and put reflective tape on anyone walking outside after dark.
14. Classic Monster Group Costume
Hand out a vampire, werewolf, mummy, ghost, skeleton, swamp creature, stitched monster, witch and monster bride, and build each one from layers rather than heavy masks. The vampire wears a dark suit and cape; the werewolf brown clothing, faux-fur cuffs, ears and messy hair. Mummy strips should stop above the shoes, and I tack them down at a few points with a needle, because loose wraps unravel by the second hour. Pale, grey, green and purple makeup tells the monsters apart without anything graphic. A little black on everyone holds the lineup together.
15. Colorful Witch Coven Costume
A coven where every witch wears her own colour avoids the sea-of-black problem in photos. Each person picks purple, green, blue, orange, pink, silver or black for a dress, a blouse and skirt or a jumpsuit, then adds a matching pointed hat, a belt, striped tights and ankle boots. Star decals, shimmer and dark lipstick keep it fun rather than frightening. Wrap a short broom handle in ribbon that matches the outfit, and hand out tiny cauldrons for candy. Felt hats collapse at the tip, so slip a rolled paper cone inside before you go. Same hat shape and similar boots for everyone, different colour for each witch.
16. Glam Vampire Group Costume
Glam vampires let everyone shop their own wardrobe for black dresses, dark suits, velvet jackets, lace blouses, waistcoats and tailored trousers. Each person adds a cape or capelet lined in red, purple, emerald or silver, with slicked hair, polished waves or jewelled clips. Go light on pale foundation and set it, then add smoky eyes, defined brows, a deep berry lip and small fangs. Mixed eras are fine as long as the capes share a lining colour family. Empty ornate frames, faux roses and battery candles make good props for a group shot.
17. Friendly Zombie Group Costume
Give every zombie a job before they died: cheerleader, athlete, office worker, tourist, student, chef or gardener. Thrifted clothes in faded colours with a few small tears at the hems do most of the work. Sand the hems with rough sandpaper rather than cutting them, since it frays the edge more believably. Grey-green face makeup, dark shadow and messy hair give a cartoon undead look without wounds. Props match the job, like pom-poms, menus or a watering can, and anyone can join with clothes they already own.
18. Ghost Through The Decades Group Costume
Picture friendly ghosts arriving from every decade: a 1920s flapper, a 1950s diner server, a 1960s mod, a 1970s disco dancer, an 80s aerobics fan, a 90s grunge musician and a 2000s pop look. Each person makes their era in white, pale grey or silver, with soft white makeup, silver highlight and grey shadow. Whole outfits in white are hard to thrift, so I suggest a pale base plus spray-on fabric paint in white on the trickier pieces, tested on a seam first. Comfortable era shoes and props like an old phone, a record or big sunglasses make each decade readable.
19. Pirate Crew Group Costume
Striped shirts, loose blouses, vests, cropped trousers, layered skirts and worn-looking coats make the crew, all in burgundy, navy, cream, brown and black. Bandanas, tricorn hats, hoops and wide belts turn plain thrifted clothes into a costume. Keep yarn hair pieces to braids and messy waves, not anything that imitates a culture. Smoky liner and drawn mustaches add character. Tea-dyeing a white blouse in a sink for half an hour gives it the aged cream colour cheaply. Assign a captain, navigators, deckhands and treasure keepers so nobody stands around as a spare pirate.
20. 1980s Aerobics Group Costume
Neon fills a big group fast. Layer bright tanks or leotards over opaque leggings, then add cropped sweatshirts, running shorts, leg warmers and wide belts, with each person mixing their own neons and the group repeating hot pink, electric blue, lime and purple. High side ponytails, teased curls, blue shadow and bright blush finish the decade, with white sneakers on everyone. Cut the neck out of an old sweatshirt and it slides off one shoulder the way it should. Make one person the instructor with a headset and whistle to run the photo.
21. 1970s Disco Group Costume
Flared trousers, metallic tops, wrap dresses, patterned shirts, jumpsuits and sequined jackets in silver, gold, white, purple and jewel tones fill a dance floor quickly. Feathered waves, round curls and centre parts can come from wigs, styled with respect rather than as a joke. Shimmer, gloss and glowing cheeks are the makeup. Platform shoes need a wide, stable sole; narrow vintage platforms twist ankles once the floor gets crowded. Oversized sunglasses, wide collars and mirror-ball purses pull separate thrift finds together.
22. Rainbow Color Group Costume
When nobody knows who's actually coming, use a rainbow. Each person takes a colour and builds a full outfit in it, from a dress or jumpsuit to plain separates, then repeats that shade in shoes, socks, hair accessories and jewellery. Coloured hair extensions and matching shadow make the colour stronger. Line up in order for photos, add one or two clouds in white and silver, and put someone in gold at the end as the pot of treasure. Kids and adults both decide their own coverage and footwear, and there are no names to learn.
23. Tetris Block Group Costume
Each block is a set of square panels in one colour, cut from foam board or cardboard, painted solid and marked with black grid lines. Worn over a base outfit and matching sneakers in red, blue, yellow, purple, orange or green, it hangs over the shoulders so arms and legs stay free. One person wears a black frame with white grid lines as the board itself. Foam board catches in doorways and crowds, so I score the panels and hinge them with duct tape so they fold when bumped. Practise interlocking poses at home, because they take longer than you think.
24. Domino Tile Group Costume
Dominoes suit schools and offices because the theme is clean black and white. Everyone wears a black long-sleeve top, black trousers or leggings and comfortable shoes, with white felt circles and a dividing line on the front in a different number for each person. White gloves, headbands or spotted bow ties add a little personality. Iron-on adhesive under the felt dots keeps them flat on cotton, where glue alone tends to lift at the edges. Foam board frames are optional and should come off easily. Stand end to end with the matching numbers touching for the group photo.
25. Emoji Reaction Group Costume
Every person wears a different reaction on a yellow tee, sweatshirt or tunic, or on a round foam board panel over black pants and sneakers. Big felt features show laughing, surprise, confusion, cool sunglasses, sleepy eyes, hearts or a wink, and hair and makeup can play along with a high ponytail for excitement or a sleep cap for tired. Yellow speech bubbles with short family-friendly reactions make good props. Round panels read better than tees from across a room, though they make sitting awkward; I'd only use them for a photo or a short party. Every base stays the same bright yellow.
26. Fast Food Menu Group Costume
A whole takeout menu: burgers, fries, pizza, tacos, soda cups, milkshakes, hot dogs and ice cream, each built over neutral clothes with felt, foam sheets and light cardboard. The burger is layered panels in brown, green, yellow and red; fries are a red box tunic with yellow foam strips. Food hats and headbands do a lot, and cheek makeup can match each item. Foam fries flop over by the end of the night, so I tape a bamboo skewer, trimmed blunt, to the back of each strip. One server in a striped shirt, apron and paper hat runs the lineup.
27. Garden Bug Group Costume
Butterflies, bees, ladybugs, dragonflies, caterpillars, flowers and a gardener or two make a garden that's easy for mixed ages. Insects wear tops, skirts or pants and tights in their colour, with antenna headbands and sheer fabric wings; ladybugs get black felt dots on red. Gardeners wear denim overalls, plaid shirts, sun hats and rain boots with an empty watering can. Pin hair into braids or buns that stay clear of wings. A caterpillar is a fun one for three or four people in matching hoodies linked at the waistband with safety pins. Spare people become daisies, sunflowers or mushrooms.
28. Garden Gnome Group Costume
Solid shirts, suspenders, dark pants or knee-length skirts, striped socks and brown shoes make the gnome base. The hat is the costume, so spend time on it: tall pointed felt in red or mixed colours, with a strip of fusible interfacing ironed inside so it stands up. Some gnomes wear fluffy beards; others go with braided wigs, pigtails or flowered hats. Rosy blush and freckles finish the faces. Each one carries a small garden piece like a watering can or tiny rake, and a couple of people can be mushrooms in spotted red hats.
29. Solar System Group Costume
Hand out the sun, moon, planets, stars, comets and astronauts. Each planet wears its colours, blue and green for Earth, red for Mars, plus a round panel, a labelled sash or a ring of flexible tubing. The sun wears gold and yellow with a rayed headpiece, and stars wear silver with sparkly clips. Saturn's ring is the tricky one: a hula hoop held on clear suspender straps sits level and lifts off fast. Metallic shadow and constellation dots at the temples suit everyone, and astronauts wear white coveralls with mission patches.
30. K-Pop Fantasy Hero Group Costume
Split the crew into two performance teams. One side wears jewel-tone cropped jackets, pleated skirts or tailored pants, metallic boots and bright hair streaks; the other wears red, navy and black stage suits with trim and polished sneakers. Bold liner, shimmer, cheek gems and gloss give concert makeup. Each performer carries a microphone, fan, light stick or charm, and backup dancers in matching streetwear absorb any extra people. Metallic belts repeated on everyone link the two teams. Pick silhouettes people can actually dance in, since this group will be asked to perform at least once.
Getting Twenty Costumes Into One Photo
The group shot is usually the only time anyone sees the whole idea at once, and most groups take it badly: everyone crowded together, the main characters lost in the middle and the props hidden behind someone's arm.
Arrange by height and colour
Put the tallest people and anyone with a wide panel costume at the back or the ends. Colour-based themes like crayons and rainbows need a fixed order, so decide it in advance and tell people their spot. Main characters go in the front centre where faces show.
Pick the spot before the party
A big group needs space, so find a wall, a driveway or a staircase where people can stand in two or three rows. Stairs work best because every face clears the person in front. Take the photo early in the evening, while hats still stand up, makeup is fresh and nobody has left yet.
Moving through a crowded room
Rigid panels, karts, wings and wide hats are fine for the photo and a nuisance on a busy dance floor. Build them to come off in seconds with ribbon ties or snaps rather than tape, and agree on one corner where they get stacked. Anything that blocks the eyes, from masks to tall hats, should be easy to push up when someone is walking in a crowd or on stairs.
Twenty People, One Clear Theme
The groups that hold together all have a theme people can read and roles that give everyone something to do. Colour-based ideas like crayons, rainbows and planets stretch to any size; character groups make a bigger scene but need more planning. Lock the head count before anyone buys anything, and share the palette, the shoe plan and the supply list in one place. Light props and comfortable layers make walking and posing easier. Pick a concept that fits everyone's budget, and the entrance takes care of itself.
