25 Trio Halloween Costumes
Every Halloween, someone sends the group text: “What are we dressing up as this year?” And if you’re part of a trio, you know the stakes are even higher.
It’s not just about finding a costume—it’s about syncing up like a well-tuned pop band.
Whether you’re best friends, siblings, co-workers, or a last-minute group thrown together by party logistics, these trio Halloween costume ideas will have people stopping you mid-walk to say, “That’s genius.”
Let’s dive into 25 epic trio Halloween costumes, complete with clever themes, styling tips, and real-life tricks to pull them off.
Powerpuff Girls (Blossom, Bubbles, Buttercup)
You can never go wrong channeling girl power in primary colors. Blossom’s red bow, Bubbles’ pigtails, and Buttercup’s fierce scowl are Halloween gold.
Here’s the secret sauce: it’s not about exact replicas. You can modernize the look with edgy dresses or comfy joggers. Think athleisure superhero chic.
Pro Tip:
Use temporary hair dye sprays for each character’s signature color. Easy to apply, washes out the next day, and earns you extra sparkle points.
Harry, Ron, and Hermione
You’ve got magic, mischief, and academic excellence all rolled into one trio. It’s iconic, nostalgic, and instantly recognizable.
A Gryffindor tie, wand, and a pinch of British attitude go a long way. You don’t need to rent Hogwarts robes—thrift store blazers and scarves can totally work.
Fun Fact:
According to a 2023 poll by YouGov, over 52% of millennials say Harry Potter costumes are their favorite nostalgic group look.
Alvin and the Chipmunks
Feeling mischievous? Go for color-blocked hoodies, black noses, and chipmunk tails.
Alvin’s red “A” is essential, and don’t forget Simon’s glasses or Theodore’s snacks.
This costume is comfort-level 100—hoodies, sneakers, and the freedom to break into song at random.
Anecdote:
One Halloween, my friends and I dressed as the Chipmunks and ended up singing “Witch Doctor” at a karaoke bar.
Did we win free shots for the crowd-pleasing? You bet we did.
The Sanderson Sisters (Hocus Pocus)
If you’re a trio of drama queens (in the best way), this one’s for you. Winifred, Mary, and Sarah bring the camp, the spells, and the sass.
Shop for thrifted cloaks, tacky corsets, and wig game on point. Add a plastic cauldron and a couple of potion bottles for full effect.
Tip:
Use exaggerated makeup to highlight each character’s unique look. Winifred’s overdrawn lips and Sarah’s sultry lashes are a must.
Rock, Paper, Scissors
Silly? Yes. Memorable? Absolutely. This trio costume is as low-effort as it is hilarious. Think big foam cutouts or cardboard pieces.
It’s the costume equivalent of an inside joke—you’ll be the ones laughing all night.
Secret Sauce:
Make the costumes wearable like sandwich boards so you can still dance. Trust me, no one wants to do the wobble in a stiff rectangle.
The Sandlot Kids (Benny, Squints, Ham)
Nostalgia alert. Baseball tees, caps, and vibes. Benny’s red PF Flyers are key, Squints needs glasses, and Ham’s “You’re killin’ me, Smalls!” tee is iconic.
Great for movie lovers and childhood throwbacks.
Stat:
In a 2022 costume popularity report, ‘The Sandlot’ ranked in the top 10 cult movie group costumes.
Destiny’s Child
You’re not just dressing up—you’re bringing the performance. Think coordinated but distinct outfits in glitzy fabrics.
It’s about owning your role: Beyoncé gets the spotlight, Kelly brings the harmony, and Michelle brings the soul. Add fake mics for extra flair.
Style Tip:
Stick to metallics—gold, silver, bronze—to really own that early vibe.
Mario, Luigi, and Princess Peach
Classic, colorful, and endlessly fun. Overalls, hats with initials, and a blonde wig for Peach—done.
It’s also an instant icebreaker. Someone will shout, “It’s-a me!” before the night’s over.
DIY Tip:
Use felt and hot glue to make the “M” and “L” on your caps. Cost-effective and surprisingly durable.
Shrek, Donkey, and Fiona
Embrace the green. Shrek’s iconic ears, Fiona’s red braid, and Donkey’s gray outfit bring this fairy tale to life. Bonus: it’s hilarious and oddly heartwarming.
It’s also a chance to lean into chaotic energy. Perfect if your trio thrives on goofy humor.
Personal Note:
We tried this in and people chased us down the block to take pictures. It was our most viral costume moment.
The Heathers
Time to get preppy. Red, green, and yellow plaid blazers, high ponytails, and croquet mallets—yes, really.
Dark comedy fans will adore this. It’s mean girls with a deadly twist.
Bonus:
Use phrases like “Did you have a brain tumor for breakfast?” for full immersion. Just… read the room first.
The Ghostbusters
There’s something strange in your neighborhood—so why not bust it? Khaki jumpsuits, proton packs (try cardboard and pool noodles), and nerdy glasses seal the deal.
The best part? You can be gender-neutral with it. It works with any combo of friends.
Pro Insight:
Amazon sells inflatable proton packs now. Less weight, more laughs.
Clueless Trio (Cher, Dionne, Tai)
Nothing says ‘90s like plaid skirt suits and fluffy pens. Grab some knee socks, tiny backpacks, and work that valley-girl accent.
Cher’s yellow plaid, Dionne’s hats, and Tai’s makeover moment are all rich in Instagram-worthy flair.
Pro Styling:
Go thrifting or hit up fast fashion sites—retro styles are trending, so pieces are easy to find.
Reese’s Trio: Peanut Butter Cup, Nutrageous, Fast Break
Get punny with candy costumes.
One person wears orange (Peanut Butter Cup), one brown/gold (Nutrageous), and one blue/red (Fast Break). Use iron-on vinyl or paint.
This is sweet, pun-filled fun, perfect for foodies and clever costumers alike.
Party Trick:
Hand out mini Reese’s. People will love you for it.
Charlie’s Angels
Go full spy glam in black leather, heels, and killer eyeliner. Whether you choose classic Farrah Fawcett or the reboot, this costume screams confidence.
Don’t forget those fake guns and dramatic slow-motion walk-ins.
Tip:
Create a choreographed “angel pose” for photos. Cheesy? Absolutely. Memorable? Even more so.
Mean Girls on Halloween (Mouse, Bunny, Cat)
Say it with me: “I’m a mouse, duh.” This one is all about tongue-in-cheek minimalism.
Wear anything black and add ears. The joke lands because it’s simple.
Quick Add-On:
Use face paint to add a nose and whiskers. It’s subtle, but helps complete the look.
The Three Blind Mice
Gray sweats, mouse ears, canes, and black sunglasses. This one’s super comfy and totally adorable.
Bonus: It works great for indoor parties or colder climates.
Real Talk:
I once saw three moms wear this on a trick-or-treat route. Kids loved it, and so did the neighbors. Easy, safe, and endlessly clever.
The Scooby-Doo Gang (Choose Three)
Pick your top trio—Velma, Daphne, and Shaggy is a great combo. Each character has strong visual cues: orange turtleneck, purple dress, green tee.
It’s recognizable, fun, and great for mystery lovers.
Budget Tip:
All you need is colored basics and a DIY magnifying glass. No full costume purchase necessary.
Three Fairies (Think: Flora, Fauna, Merryweather)
These magical ladies from Sleeping Beauty are the fairy godmothers of Halloween charm. Red, green, and blue dresses, sparkly wands, and pointy hats.
It’s perfect for a trio of friends who love whimsy and enchantment.
Styling Hack:
Use tulle for the capes and dollar-store wands for a cute but affordable touch.
The Kardashians
Love them or not, they make a killer trio costume. Choose three sisters and go full glam—bodycon dresses, sunglasses, and bold contour.
Perfect for friend groups who want to serve looks and attitude.
Pro Move:
Don’t forget to pose with duck lips and iced coffees.
The Three Stooges
Slapstick fans, rejoice. Moe, Larry, and Curly bring vintage vibes and classic comedy gold.
You’ll need wigs, suspenders, and a commitment to funny faces and shenanigans.
Acting Tip:
Practice the slap routines (without actually slapping anyone!)—theatrical antics win big.
The Addams Family (Wednesday, Morticia, Gomez or Uncle Fester)
Spooky, kooky, and totally iconic. Go goth chic with all-black outfits, dark lipstick, and a deadpan expression.
If you’re trio-ing with family or a couple, this one delivers serious Halloween cred.
Photo Op Tip:
Go grayscale for your group pics to really nail that creepy aesthetic.
Alvin, Simon, Theodore—but Make It Zombies
Twist the classic chipmunks into spooky territory with ripped hoodies, pale face makeup, and fake blood.
Great if your group wants to go funny-meets-ghoulish.
Fun Add-On:
Add fake acorns dripping in red syrup. Gross? Yes. Effective? Absolutely.
Pac-Man and Ghosts
One person dresses as Pac-Man (yellow circle, simple cutout), and the other two as ghosts (pink and blue sheets or ponchos with big eyes).
It’s instantly recognizable and great for dance floors—Pac-Man chases ghosts all night.
Party Trick:
Sync your movements to old arcade sound effects from a Bluetooth speaker.
The Golden Girls
Comedic gold with pearls and gray wigs. Blanche, Dorothy, and Rose (or Sophia!) are a timeless trio.
Perfect if your group loves dry wit, old-school charm, and fabulous vintage fashion.
Comfort Tip:
Go for thrifted housecoats and orthopedic shoes. Your feet will thank you.
The Weather: Sunny, Cloudy, Rainy
Use yellow for sun (add sunglasses), gray for clouds (cotton balls), and blue for rain (with dangling raindrop cutouts).
It’s quirky, unexpected, and full of personality.
Creative Twist:
Add sound effects—thunder booms, wind noises—on a portable speaker for full immersion.
Final Words
At the end of the night, Halloween isn’t just about the costume.
It’s about shared creativity, inside jokes, the rush of compliments, and how you felt walking into that party.
When you’re part of a trio, you’re not just dressing up—you’re telling a mini story.
And trust me, nothing bonds a group faster than hot-gluing felt letters to a hoodie 30 minutes before the Uber arrives.
So pick your vibe: sweet, spooky, satirical, or stylish. Then commit. Own it. And if all else fails? Just be three bananas. Everyone loves bananas.
Happy haunting, you brilliant trio.
