Best Group Costume Ideas for Adults

1. Egyptian Costumes 

Cleopatra always made an entrance and so will you. Choose your Cleopatra queen and then assign who can be a pharaoh or a mummy. Got more people, add more mummies or even Ra, the Sun God. If you want to DIY, grab a white sheet for a robe and layer on gold jewelry or metallic fabric. Or skip the hassle and buy a full matching set online.

2. Greek Gods and Goddesses 

Group costume ideas with Greek ethereal beauty? Easy. Togas made from bedsheets, gold headbands and a few props like lightning bolts or tridents are all you need to become the gods of Mount Olympus. Zeus, Aphrodite or Hades, there are plenty of Gods to choose from. 

3. The Sanderson Sisters

It’s not Halloween without these three. The hardest part is choosing which sister you want to be and the rest is just a bunch of Hocus Pocus. You can find premade costume sets or thrift and customize your own. You’ll need three minimum to pull this off. 

4. Powerpuff Girls 

Another trio to choose from: Blossom, Bubbles or Buttercup? All you need are colorful dresses (pink, blue, green), white knee socks and a little attitude. If you’ve got a fourth friend, have them go as Mojo Jojo for bonus laughs.

5. Barbie

With all the Barbie movie hype, Barbie group costume ideas are having a moment. Let everyone choose their favorite Barbie style; there are over 250 career-themed Barbies alone, not to mention classics like Rollerblade Barbie and Mermaid Barbie. Don’t forget all of the Ken options, too. Something a bit more quirky? You can even find Barbie costumes that look like the boxes the dolls come in. Or, you could DIY by thrifting fun pink outfits and box accessories. 

6. Anchorman Crew

If your group thrives on sarcasm and outdated suits, the Anchorman news team is a go-to group costume idea. Grab mustaches, polyester and bad pickup lines — the 2000s nostalgia hits just right. You can find secondhand polyester suits or fake microphones to really sell the bit. Anyone who’s seen the movie will recognize it right away. You’ll need four people to pull this off — Ron Burgundy, Brick, Brian and Champ.

7. M&M’s

Choose your favorite color and roll in as everyone’s favorite candy. Grab a colored tee and stick on a giant “M,” and you’re done. This is a go-to for last-minute Halloween costume ideas. 

8. Pie Slices

Looking for group costume ideas that are super easy and lean into the cutesy vibe? Make a pie out of it. Everyone picks a flavor (apple, cherry, pumpkin) and wears matching triangle-shaped costumes. You can even make them yourself with paint and cardboard or order premade food costumes. Bonus points for whipped cream hats.

9. Astronauts

Up, up and away! If you need group costume ideas that are truly out of this world, grab some space suits and helmets and get ready to soar. You can buy matching NASA suits online or make your own with white hoodies, duct tape and printed mission patches. It’s great for all ages and easy to expand for large groups.

Funny Group Costume Ideas

10. Traffic Cones

Everyone will stop (pun intended) because there’s something absurdly hilarious about six adults waddling into a party dressed like road cones. It works best in groups because the more cones, the more ridiculous the visual.

All you need are bright orange shirts or dresses plus orange party hats. Add a sign that says “Detour” or “Construction Zone” for extra laughs. Cheap, easy and great for 2 to 6 people. If it’s just you and one other person, you could stand on either side of the door and direct people where to go as they enter the party.

11. Roller Coaster

One of the most popular group costume ideas in recent years. Tape together cardboard seats, throw your hands up and scream. You’ll need 3 or more people to really sell the ride illusion.

12. Smurfs and Smurfettes

You'll need blue shirts or face paint, white pants and floppy white hats (you can DIY them from felt or order online). The more Smurfs you add, the more village energy it gives. Throw in Papa Smurf or Gargamel if you're feeling ambitious. It works best with at least three people to give that “village” feel, and you can add Papa Smurf, Brainy or even Gargamel if you want to expand the cast. 

13. Fast Food Items

Fast food items are classic group costume ideas that never get old. Let everyone choose their favorite food or make it a coordinated effort (like ketchup, mayonnaise and mustard for a three-person group, for example). Easiest to pull off with t-shirts and cardboard signs, but full-body costumes are easy to find on Amazon, too.

14. Crayons

Each person picks a color and wears matching outfits with DIY “Crayola” labels. You can make them with solid-colored T-shirts, iron-on letters and pointy party hats for the crayon tips. Most supplies are at dollar stores or craft shops.

15. Alcoholic Beverages 

Dress as wine, beer or a cocktail for these cheeky group costume ideas. It’s probably not the best choice if you need group costume ideas for work, but it’s great for most other parties. You can buy pre-made online or craft something unique out of cardboard.

16. Crash Test Dummies

If you’re looking to get creative with your group costume ideas, this one will have everyone rolling. Suit up in matching yellow jumpsuits with black detailing and painted-on targets. It works best if you’ve got a group, and it’s even funnier if you lean into robotic walking and exaggerated movements.

17. French Kiss

One of the wittiest pun costumes: dress as the band KISS (face paint, black outfits) but add berets, striped shirts and baguettes. When it comes to funny group costume ideas, this one is sure to get some laughs.

Group Costume Ideas for 4 People

18. The Beatles

Group costume ideas for 4 don’t get more legendary than The Beatles. Pick your era — the early mop-top days with matching suits or go full psychedelic with the bright Sgt. Pepper uniforms. Add props like toy instruments, retro sunglasses or fake mustaches for extra detail. Bonus points if one of you brings a speaker and plays their greatest hits.

19. Star Trek

You can buy Starfleet uniforms or mimic them with solid-color tees and insignia stickers. Don’t forget the Vulcan salute. Good for 4 or more.
