That’s the tricky part with office Halloween: it has to be creative, a little spooky, but still work-safe. Over the years, I’ve found that small spaces push us to be more resourceful, and the same goes for group costumes—when the setting is a professional one, boundaries can spark some of the most clever ideas. So here’s my list of 10 group Halloween costume ideas that have worked like magic at the office.We once used a simple room planner to map out our costume staging area—because yes, even costumes need layout planning in a busy office.1. The Classic Movie CastPick a film everyone loves—think Ghostbusters or The Wizard of Oz. It’s a crowd-pleaser and gives each person a distinct role. The challenge? Agreeing on the actual movie without starting an office debate rivaling the coffee brand wars.save pin2. Pack of EmojisYellow T-shirts, printed emoji faces, and you’re instantly Instagrammable. It’s comfortable for all-day wear and office-friendly. Just be sure to avoid the more... expressive emojis.save pin3. Deck of CardsOne shirt per suit, numbers or face cards on top. It’s cheap, scalable to any team size, and gives you the perfect excuse for a midday Magic Trick Show.save pin4. Famous Painters & ArtworksHalf of you dress as painters (Van Gogh, Frida Kahlo) and the rest as their iconic works. Great conversation starter—but prepare to explain Starry Night to that one coworker who “doesn’t do museums.”save pin5. Office Supply AvengersMix superhero elements with oversized stationery—giant paperclip shields, stapler gauntlets. We once designed oversized props using a free floor plan creator to visualize proportions before crafting them.save pin6. Board Game PiecesEach person takes on a Monopoly token, Clue character, or giant Scrabble tile. It’s colorful and quirky, but you’ll need space to store pieces if they’re big.save pin7. Decades MashupAssign each person a time period—’20s flapper, ’70s disco, ’90s grunge. It’s nostalgic and great for mixed-age teams, though watch the budget if you’re renting costumes.save pin8. Famous Duos & Trios ExpandedStretch the idea so more people can join—Peanut Butter & Jelly & Bread, for instance. The cheesier the pun, the better the laughs.save pin9. Spooky Office TakeoverThink Haunted Receptionist, Phantom Accountant, or Skeleton CEO. We once planned the cubicle decoration layout with a kitchen layout planner—because the space planning was eerily similar to arranging an open-plan office.save pin10. The Weather TeamSun, rain, storm, rainbow—everyone picks an element and dresses accordingly. Fun for team photos, but someone has to commit to being the cloud all day.save pinFAQ1.
