10 Fun Office Group Costume Ideas: Creative and hilarious themes to make your workplace Halloween unforgettable

One time, our marketing team decided to show up as a fruit basket — I was the watermelon (don’t ask). The laughter lasted all day, but so did the itch from my DIY cardboard. That’s when I realized group costumes are an art: they need to be fun, comfortable, and easy enough for even your least crafty coworker. Small spaces — like a crowded office — can spark big creativity if you play it right. So here are my 10 favorite office group costume ideas, from experience and a bit of trial‑and‑error.

1. Classic Movie Cast

Think “The Wizard of Oz” or “Ghostbusters.” Easy to recognize, works for any team size, and people love taking photos with you. The only challenge is making sure no two people fight over the same character. You can map the arrangement in a shared visual board, similar to how I once used a room planner to sort team seating for an event.

2. Decades Throwback

Each person dresses from a different decade — '70s disco, '80s neon, '90s grunge. It’s low‑pressure, as each person styles their own outfit. The fun is in the mix, but you might get a few “What decade are you supposed to be?” questions.

3. Deck of Cards

Perfect for large offices. You can split into suits or all come together for a giant group photo. Affordable if you print oversized cards and tape to plain t‑shirts.

4. Emoji Squad

Pick your favorite emoji and print it on foamboard or cardboard. It’s fast, light, and social‑media gold. Just make sure someone claims the “poop” emoji willingly.

5. Iconic Duos, Multiplied

Salt & Pepper, Batman & Robin, Peanut Butter & Jelly — but with multiple pairs in one team. It’s interactive, and you can even stage “pair switch” moments for fun. I once planned this theme like I was using a free floor plan creator to ensure couples were evenly spread across the office.

6. Board Game Pieces

From Monopoly tokens to chess pieces, everyone gets a role. Bonus if you bring a life-size game board for meeting room fun. It can be prop‑heavy, so plan storage in advance.

7. TV Newsroom

Reporters, anchors, weather presenters — even the “on‑location” correspondent in a raincoat. Very easy for business settings, since many outfits can be created with what you already have.

8. Tourist Invasion

Hawaiian shirts, cameras, floppy hats. Inexpensive, hilarious, but watch out for colleagues using “character” as an excuse to slack off.

9. Superhero Mash‑Up

No need to be from the same universe — Marvel meets DC meets… your own made‑up hero. Works for both store‑bought and DIY capes. I once used a kitchen layout planner style grid to organize who brings which props so we weren’t drowning in plastic shields.

10. Black & White Ball

Dress code: only black and white. Add masks to make it spooky. It’s chic, minimal, and perfect for a polished group photo in the office lobby.
