How to pick the right idea

Run every idea through three quick checks:

1. Does it fit our number? Don't force a 4-person idea on 6 people.
2. Is it school-safe? No masks that cover the whole face, no fake weapons, nothing too revealing, if you're wearing it to school.
3. Can we mostly closet-shop it? If every person has to buy a full outfit, it gets expensive fast.

For the planning side (budget, roles, deadlines), read how to plan a group costume.

1. The Powerpuff Girls. Pink, blue and green dresses or tees, matching hair accessories.

These group costume ideas for 4 teens work well because so many famous groups come in fours.

Ideas for 6 or more

The bigger the group, the more a flexible theme helps.

30. Deck of cards. Each person is a different card; add more cards as more people join.
31. Candy box. Each person is a different candy, with a label.

36. A school yearbook. Everyone dresses as a "most likely to" superlative.

The tricky part with 6+ people is keeping track of who's covering which piece, because it's all buried in the chat. Viralinc's The Costume Rack is its costume app, so your group has one starting point instead of scrolling back through old messages. Find your app

School-friendly ideas

Group costume ideas for school and high school need to pass the dress code. These are safe bets:

37. Crayons or highlighters. Solid colors, nothing tricky.
38. Emojis. Just tees and markers.
39. Board game pieces. Monopoly tokens or Candy Land characters.
40. Teachers' pet theme. Everyone dresses as a different subject (science goggles, math equations, an art smock).

Also good for group halloween costume ideas for teen boys who don't want face paint or anything fussy: sports lineups, chess pieces, the TMNT hoodies or fast food mascots.

Always check your school's rules. If in doubt, ask a teacher before the day.

Split the pieces fairly

Some roles are easy (wear a green tee) and some take work (build a cardboard creeper). Keep it fair:

• Balance the effort: the person with the easy costume brings shared stuff like face paint or a group sign.
• Set a budget per person and stick to it.
• Closet-shop first: swap pieces between friends before buying anything.
• Write it down: a shared list with each person, their role and what they still need.
