Iconic Trio Halloween Costumes That’ll Make You the Talk of Every Party
Contents
I’m gonna be real with you—finding the perfect trio costume is way harder than it should be.
One friend wants something cute, another wants scary, and you’re just trying to make sure you all look good together without spending your entire paycheck.
Been there, done that, got the mismatched costume photos to prove it.
But here’s the thing I’ve learned after years of group costume fails and wins: the best trio costumes are the ones where everyone feels confident AND people instantly know who you’re supposed to be without you having to explain it seventeen times.
So let me walk you through some iconic trio halloween costumes that actually work in real life, not just on Pinterest boards.
Why Trio Costumes Hit Different
There’s something about showing up with your two best friends in coordinated outfits that just feels right.
You’re not doing the awkward solo costume thing where you have to introduce yourself as “sexy corn” or whatever.
And you’re not trying to wrangle eight people into agreeing on one theme either.
Three is that perfect number where you can actually coordinate without losing your mind in a group chat.
Plus, let’s be honest—the photos always turn out better when there’s three of you.
Classic Movie Trios That Never Get Old
The Sanderson Sisters from Hocus Pocus
Okay so this one is basically the holy grail of trio costumes.
Winifred, Sarah, and Mary are instantly recognizable, and honestly? The costumes are fun to put together.
You’ll need some long colorful capes for that witchy vibe, and honestly the hair is half the battle here.
Winifred gets that iconic red updo (wig recommended unless your hair defies gravity), Sarah rocks the long blonde waves, and Mary gets the darker reddish-brown with that weird side part thing going on.
The best part? You can go full costume with the corsets and period-accurate dresses, or you can do a modern take with black outfits and just nail the hair and makeup.
I’ve seen both work really well.
Mean Girls – The Plastics
If you and your girls want something that’s more fashion than costume, this is your answer.
The iconic “On Wednesdays we wear pink” scene gives you the easiest costume brief ever—literally just wear pink.
But if you wanna take it up a notch, go for the specific looks from the movie.
Regina in her pink polo and white jacket.
Gretchen in that pink cardigan situation.
Karen in… well, whatever pink thing Karen was wearing because let’s be real, she was just happy to be there.
You can grab some cute pink tank tops and layer them with what you already own.
Add a Burn Book as a prop and you’re golden.
Clueless – Cher, Dionne, and Tai
This one’s for my 90s fashion lovers who’ve been waiting for an excuse to wear plaid everything.
Cher’s yellow plaid outfit is iconic, but honestly any of their looks from the movie work.
The key elements you need:
- Plaid skirts or blazers
- Knee-high socks
- Platform shoes or Mary Janes
- Those tiny 90s shoulder bags
- Hair clips (the more the better)
Tai can rock the flannel-over-dress combo from her makeover scene, and Dionne obviously needs that amazing black and white houndstooth situation with the matching hat.
The fashion in this movie was so good that you literally can’t go wrong.
Pop Culture Trios That Everyone Will Recognize
Euphoria – Maddy, Cassie, and Kat
If you want something current and you’re into makeup, this is your moment.
Euphoria gave us some of the most memorable looks in recent TV history.
Maddy’s bold makeup and confident style.
Cassie’s softer, more romantic aesthetic.
Kat’s edgy transformation throughout the series.
You can pick specific episodes or just embody their general vibes.
Stock up on glitter eyeshadow palettes because Euphoria makeup doesn’t do subtle.
The best part about this costume is you can wear stuff you’d actually wear to a party anyway—just turn the drama up to 11 with the makeup and accessories.
Stranger Things – Eleven, Max, and Robin
There’s so many trio options from Stranger Things honestly.
But I love this combination because each character has such a distinct style.
Eleven in her season 3 mall outfit with that colorful romper and yellow shirt.
Max in her casual 80s skatergirl vibe.
Robin in her Scoops Ahoy uniform (iconic) or her band geek aesthetic.
You could also do the boys—Mike, Dustin, and Lucas—if you want that 80s kid adventure vibe.
Just raid a thrift store for vintage windbreakers and you’re halfway there.
Wednesday Addams, Morticia, and Pugsley (or Gomez)
The Addams Family is having a moment again thanks to the Netflix series.
And honestly? All-black costumes are the easiest thing ever.
Wednesday needs her braids, black dress, and deadpan expression.
Morticia gets the long black gown and that impossibly sleek hair.
And then whoever’s playing the third can choose—Pugsley in his striped shirt, or Gomez in a pinstripe suit.
The best thing about Addams Family costumes is you probably already own 80% of what you need.
Nostalgic Animated Trios
Powerpuff Girls – Blossom, Bubbles, and Buttercup
This costume never gets old because it’s so simple but so effective.
You need three dresses: pink, blue, and green.
Add some black tights or leggings, black shoes, and you’re basically done.
You can find simple colored dresses pretty much anywhere.
The real commitment comes if you wanna do the hairstyles—Blossom’s bow and ginger hair, Bubbles’ blonde pigtails, and Buttercup’s black bob.
But even without perfect hair, people will know exactly who you are.
I’ve seen groups do modern fashion takes on this too, where they just coordinate their regular outfits in the signature colors.
Works just as well and way more comfortable for a long night.
Totally Spies – Sam, Clover, and Alex
If you remember watching this show growing up, you already know how iconic these spy suits are.
The color coordination is built right in—red, yellow, and green.
You can go full bodysuit if you’re feeling ambitious, or just coordinate colorful outfits in those colors.
Add some spy props like fake phones or gadgets and you’ve nailed it.
This one’s great because most people who grew up in the 2000s will instantly recognize it, but it’s not overdone like some other costume choices.
