Can’t decide on a single theme? Why not have everyone do their own thing within a general category of goddesses or magical beings? This allows for individual creativity while still feeling like a cohesive group. It’s a great collection of ideas for a group that wants to showcase their individual styles.

Get ready to build some fun with a Minecraft-themed trio. Dressing up as three Steves (or Alexes!) is a hilarious and surprisingly easy costume idea. The pixelated look is instantly recognizable to gamers of all ages, making it a great choice for a family or group of friends.
The key to this costume is the blocky, pixelated head. You can create one using a cardboard box painted to look like the character’s face. For the body, a simple light blue t-shirt and blue jeans are all you need. Don’t forget a pixelated foam pickaxe or sword!
23. Spooky Squad Scout Costumes

For a look that’s a little bit spooky and a little bit preppy, try a Spooky Scout trio. Think Wednesday Addams goes to summer camp. This is a unique and stylish idea that’s easy to coordinate. It’s a great option for a creative group of friends looking for fun ideas for college events.

Throw it back to the golden age of anime with a vintage-inspired trio costume. Think 80s or 90s classics with their distinct, dramatic art styles. This is a very unique choice for a group of dedicated anime fans who want to stand out from the crowd of mainstream characters.
Research is key here. Pick a specific show and characters, and pay attention to the details of their outfits and hairstyles. This often means big hair, shoulder pads, and bold color combinations. Wigs and thoughtful prop creation will really sell this nostalgic look.

27. Inside Out Trio Costume Wigs

Show your true emotions with a trio costume inspired by Disney’s Inside Out. Joy, Sadness, and Disgust make for a colorful and expressive group. While the full outfits are great, the real key is the hair. This is a fantastic set of ideas for a group that wants to focus on amazing hair and makeup.
