Two people in matching costumes get a smile. Three people in a costume that clicks? That gets the whole room cheering.
Trios hit differently. There’s more to look at, more to recognize and way more fun in the photos.
The catch is that three people have to agree on one idea. That’s usually the hard part.
So this list makes it easy. Every trio here is instantly recognizable, and every one can be made from thrift finds, craft store basics and stuff already in your closets.
We’ve also added who plays who and a rough DIY cost, so you can pick fast and start building tonight.
Keep scrolling for number 4. It’s the cheapest costume here and the one that turns into a party game. And number 12 might be the funniest trio costume ever invented.
Let’s find your three.
How to split a trio costume fairly
Before you pick, settle three things with your group.
Who wants to be the star? Some trios have one lead character. Make sure someone actually wants that role.
Who hates face paint? Give that person the character that needs it least.
What’s the budget? Agree on a number per person so nobody ends up spending double.
Five minutes of planning saves a lot of drama later.
1. Snap, Crackle and Pop
Cereal box nostalgia is always a crowd-pleaser.
Snap wears a baker’s hat. Crackle wears a striped stocking cap. Pop wears a marching band hat or a tall military-style cap.
Everyone wears bright tops with felt letters on the chest.
Carry a cereal bowl or a jumbo box, and hand out mini cereal packs if you want a cute extra.
Who plays who: the tallest person makes a great Pop.
DIY cost: about $15 to $25 each.
Pro tip: use the same shade of red or blue on all three tops so you look like one set.
2. The Sanderson Sisters
The ultimate Halloween trio, especially after Hocus Pocus 2 brought the sisters back into everyone’s feed.
Winifred wears green with a big, curled red wig and buck teeth. Mary goes red with a tilted updo and a crooked smile. Sarah wears purple with long blonde waves.
Layer thrifted skirts, corsets and capes.
Props make it: a broom, a vacuum and a big spellbook.
Who plays who: the most dramatic person in the group should be Winifred. No debate.
DIY cost: $25 to $40 each, mostly wigs.
Pro tip: learn the first line of “I Put a Spell on You.” You will be asked to perform it.
3. The Three Musketeers
Swashbuckling, easy to move in and great for any age.
Start with white blouses or shirts, add knee-high boots and dark pants. Make simple tunics from fabric with a cross painted or glued on the chest.
Feathered hats and foam or cardboard swords finish it.
Match your tunics, or give each musketeer a different colored sash.
Who plays who: anyone works. Add a fourth friend as D’Artagnan if someone wants to tag along.
DIY cost: $20 to $30 each.
Pro tip: practice one dramatic “all for one” sword pose for photos.
4. Rock, paper, scissors
Here’s the budget king we mentioned.
Each person carries or wears a big version of their hand sign. Cut the shapes from foam board or cardboard and paint them bright.
Wear black or neutral clothes underneath so the props pop.
The best part? You can play rounds all night. Strangers will challenge you.
Who plays who: the paper costume is flat and light, so give it to whoever will dance the most.
DIY cost: under $10 each.
Pro tip: attach each prop with straps like a backpack so your hands stay free.
5. Alvin and the Chipmunks
Cute, cozy and full of personality.
Alvin wears a big red sweater with a felt “A.” Simon wears blue with glasses. Theodore wears green and looks as sweet as possible.
Add brown leggings, little chipmunk ears on headbands and a touch of face paint for whiskers.
It’s as comfortable as wearing your favorite sweatshirt.
Who plays who: the loudest friend is Alvin, obviously.
DIY cost: $15 to $25 each.
Pro tip: size up on the sweaters. The oversized look is the whole charm.
6. Harry, Ron and Hermione
Easy to recognize and easy to build.
Start with school-style basics: gray sweaters, white shirts, dark pants or skirts and house-colored scarves.
Harry needs round glasses and a lightning bolt scar. Ron wears a maroon sweater with an “R.” Hermione gets a cardigan, big hair and a wand in hand.
Add black robes if you want to go the extra mile.
Who plays who: the person with the curliest hair is Hermione.
DIY cost: $15 to $30 each.
Pro tip: carry a Marauder’s Map printout or a chocolate frog box for a fan-favorite detail.
Keep going. Number 12 is coming, and it’s a trio people love to see.
7. Three blind mice
Adorable, a little cheeky and really cheap.
Everyone wears gray tops and bottoms, felt mouse ears on headbands and dark sunglasses.
Paint dowels white for canes, and pin on rope or felt tails.
Walk in a little line for photos. It gets a laugh every time.
Who plays who: it’s three of the same, so no fights here.
DIY cost: $10 to $15 each.
Pro tip: draw tiny whiskers with eyeliner for a finished look.
8. Shrek, Fiona and Donkey
Silly, nostalgic and loved by every age group.
Shrek needs green face paint, a brown vest, a loose shirt and those famous ears. Fiona wears a green gown and a tiara, with a little green makeup if she’s in ogre mode.
Donkey wears gray with ears and a big, toothy grin.
Carry a toy dragon or an “onions have layers” sign for bonus laughs.
Who plays who: Donkey should go to the funniest person you know.
DIY cost: $20 to $35 each.
Pro tip: use a water-based green face paint. It’s easier to remove at 2 a.m.
9. Huey, Dewey and Louie
Bright, breezy and great for dancing.
Match red, blue and green shirts with same-colored caps. White shorts or pants and yellow socks nod to the duck feet.
Add felt bills if you want a playful upgrade.
Props like binoculars or a treasure map fit their adventure vibe.
Who plays who: whoever loves red gets Huey.
DIY cost: $10 to $20 each.
Pro tip: a group of three bright colors looks amazing in photos, even from far away.
10. The Powerpuff Girls
Sugar, spice and everything nice.
Blossom wears pink with a big red bow. Bubbles wears blue with pigtails. Buttercup wears green with a short, sharp bob.
Everyone adds a black belt, white tights and black Mary Janes.
Strike their signature flying pose and you’ll get photos all night.
Who plays who: match the hair you already have if you want to skip wigs.
DIY cost: $20 to $30 each.
Pro tip: big, round eye makeup gives you that cartoon look.
11. Ghostbusters
A timeless pop culture trio.
Wear tan jumpsuits, coveralls or khaki separates. Add Ghostbusters patches and black boots.
Build proton packs from cardboard boxes, dryer tubing and a bit of spray paint.
Light-up details take it to the next level.
Who plays who: anyone. Name tags let you pick your favorite character.
DIY cost: $25 to $40 each, depending on the packs.
Pro tip: use backpack straps for the proton packs so they stay comfy all night.
12. The Golden Girls
And here it is. Pure sass and cheesecake.
Dorothy, Rose and Blanche come to life with vintage blouses, slacks, big jewelry and gray or teased wigs.
Dorothy gets glasses and oversized layers. Rose wears soft pastels. Blanche goes glamorous with big earrings.
Carry a cheesecake slice or teacups. Then stay in character all night.
Who plays who: the wittiest one is Dorothy, the sweetest is Rose, and the flirt is Blanche.
DIY cost: $20 to $35 each at a thrift store.
Pro tip: practice a few one-liners. That’s what makes this costume legendary.
