10 Fun Office-Themed Costume Ideas: Creative, quirky, and totally workplace-appropriate costume inspiration from my design desk

Once, during an office Halloween, I showed up as a giant sticky note—bright yellow, covered head-to-toe with scribbled reminders. It wasn’t glamorous, but the laughs I got were priceless. That day taught me something: small spaces—and small budgets—can spark the biggest creativity. In design and in costumes, working with what you have can lead to the most memorable results. So today, I’m sharing 10 office-themed costume ideas that are clever, budget-friendly, and make the workplace a lot more fun.

1. The Human Desk

Grab a cardboard box, cut out arm holes, and decorate it with fake paperwork, pens, and even a coffee cup glued on. You’ll make people do a double take, and there’s plenty of room to stash snacks inside.

2. Retro Secretary

Think 1950s pencil skirt, cat-eye glasses, and a scarf in your hair. It’s a charming nod to classic office culture, though you might get asked to type imaginary letters all day.

Cover yourself in colorful sticky notes with funny faux tasks written on each. Bonus: you’ll be the most interactive costume in the room, especially if coworkers add their own.

If you love creating visual setups for costumes like this, you’d probably enjoy using a room planner for thematic party spaces too.

6. Office Plant

Dress all in green, add a fake foliage headband, and carry a pot around your waist. Careful near photocopiers—they might block your light! You can even design the perfect leafy backdrop using a free floor plan creator before setting up the team photo area.

10. The Zoom Call

Split your outfit in two: business on top (shirt, tie or blouse), pajamas on the bottom. Add a laptop frame around your face for authenticity. You can even pre-plan the background for group pics using a kitchen layout planner just for fun—yes, even if it’s not a kitchen space, the tools work creatively for any backdrop.
