Halloween costumes are fun, but group costumes? That’s where the magic happens. There’s just something about walking into a party with your squad all dressed in a coordinated theme that makes you feel like you’ve already won the night. And let’s be honest—half the fun is planning the look and figuring out who’s going to be who. (If you’re the “mom friend,” you’re probably in charge of the snacks and the costume shopping, right? Been there.)
I’ve always loved group costumes because they give everyone a chance to shine while still pulling off one big, epic idea together. Plus, they make for some ridiculously good Instagram pics. So, if you and your besties are hunting for something fun, creative, and not overdone, I’ve got you covered. Here are 10 unique group Halloween costume ideas for teenage girls that will keep things fresh, stylish, and just spooky enough.
1. The Elements (Earth, Air, Fire, Water)
Ever wanted to embody your zodiac sign or just channel your inner Avatar: The Last Airbender vibes? Dressing up as the four elements is both unique and aesthetic.
- Earth: Green and brown outfits, leafy crowns, earthy makeup tones.
- Air: Flowing whites and silvers, light sparkly makeup, airy fabrics.
- Fire: Bold reds and oranges, glitter, and maybe even flame-shaped accessories.
- Water: Blues and teals, mermaid vibes, wavy hair.

The best part? You can totally DIY these with clothes you already own. Plus, if your group has more than four people, just add Sun, Moon, or Stars for extra celestial flair. Cool, right?
2. Pop Icons Through the Decades
Imagine this: each friend picks a decade and dresses as the ultimate pop diva from that era. One of you could rock Madonna’s ‘80s look while another channels Britney Spears circa the early 2000s.
- 1950s: Think Audrey Hepburn chic.
- 1970s: Disco queen with sequins.
- 1990s: Spice Girls, duh.
- 2000s: Low-rise jeans and butterfly clips.
It’s nostalgic, fun, and lets each person epress their style while keeping the theme consistent. Ever notice how these looks are actually coming back into fashion anyway? Perfect excuse to raid your mom’s closet.
3. Fairytale Villains
Forget the princesses—villains always have more fun. Imagine your group as Maleficent, the Evil Queen, Ursula, and Cruella de Vil strutting into the party together. That’s drama, that’s power, that’s Halloween.
- Makeup: Go bold. Dark eyeliner, red lips, glittery shadows.
- Accessories: Crowns, staffs, or a plush Dalmatian (sorry Cruella).
- Vibe: Fierce, fabulous, and a little bit wicked.
Honestly, no one’s going to forget a group of teens serving villain realness.
4. Classic Candy Crew
Why not sweeten things up? Each person dresses as a different candy—M&M’s, Skittles, Reese’s, Hershey’s bar, you name it.
- Easy DIY: Solid-colored shirts + felt cutouts = instant candy.
- Fun Factor: You’re basically living, walking trick-or-treat bags.
- Bonus Idea: Add a friend as a trick-or-treat bucket for extra laughs.
It’s cheap, cheerful, and everyone will instantly get the reference.
5. Netflix Binge Squad
Raise your hand if you’ve ever spent an entire weekend binging shows with your besties 🙋♀️. Perfect. Each person can pick a character from a Netflix hit:
- Stranger Things: Eleven, Max, or even Demogorgon if you’re brave.
- Wednesday: Obviously someone has to be Wednesday Addams.
- Outer Banks: Chill beach vibes.
- Bridgerton: Ball gowns, baby.
The mix-and-match nature of this one makes it super versatile—and you’ll instantly get bonus points for being current.
6. Emoji Squad
Simple? Yes. Boring? Nope. Dressing as emojis is hilarious and actually pretty flexible.
- ❤️, 😂, 😎, 👻, 🍕—the options are endless.
- Use face paint, cardboard cutouts, or custom t-shirts.
- Go
full-on with accessories that match your emoji (pizza slice prop, anyone?).
This one also works for bigger groups because, let’s face it, there are more emojis than we’ll ever use in our lifetime.
7. Retro Arcade Characters
This one is for the gamer girls out there. Pac-Man and the ghosts? Iconic. You could also throw in Mario, Luigi, and Princess Peach if your group wants a mashup.
- Colors: Bright, bold, and easy to DIY.
- Props: Fake coins, pixelated accessories.
- Energy: Playful and nostalgic.
Tell me you don’t love the idea of chasing each other around the party like it’s an actual arcade game. 😂
8. Mythical Creatures
Unicorns, mermaids, fairies, and dragons—this theme gives everyone the freedom to go wild with colors, makeup, and glitter.
- Unicorns: Rainbow wigs, horns, and pastel clothes.
- Mermaids: Sequined skirts, shell tops, and beachy waves.
- Fairies: Wings, flower crowns, and sparkles.
- Dragons: Darker tones, scales makeup, fiery vibes.
It’s basically a chance to live out your Pinterest board dreams for one night.
9. Famous Friend Groups
Sometimes you just want to say, “Hey, we’re iconic, and we know it.” Famous squads make perfect group costumes.
- The Plastics from Mean Girls (yes, even though they’re technically the villains, it works).
- Powerpuff Girls (cute, simple, and instantly recognizable).
- Winx Club (fairy fashion at its finest).
- Charlie’s Angels (sleek and powerful).
This idea works best if your group likes to own the spotlight. Because let’s be honest, people will definitely be quoting lines at you all night.
10. Cosmic Queens (Galaxy Theme)
For a truly unique vibe, go intergalactic. Think stars, planets, and all things space.
- Colors: Purples, silvers, and deep blues.
- Makeup: Glitter, star stickers, metallic highlights.
- DIY Props: Planet headbands, light-up jewelry.

You’ll look like a walking constellation, and honestly, who wouldn’t love that? Plus, this theme lets everyone get super creative with their own interpretation.
Tips for Pulling Off Group Costumes
Before you start hot-gluing sequins to your t-shirt at midnight (yes, I’ve done this), here are a few quick tips:
- Coordinate Early: Nothing’s worse than two friends showing up as “Earth” because no one called dibs.
- Budget-Friendly Hacks: Use thrift store finds and craft supplies instead of dropping $$$ on store-bought costumes.
- Comfort First: You’re going to be walking, dancing, and maybe even sprinting away from a creepy clown at some point—make sure you can move.
- Plan the Pics: Think about how the costumes will look in photos. Group costumes shine brightest on the ‘Gram.
