FAQ
What are good categories for an office costume contest?
Pick four or five: Funniest, Most Creative, Best DIY, Best Duo or Team, Most Desk-Friendly, and a light Scariest. Fewer categories mean every vote counts.
How do you vote in an office costume contest fairly?
One ballot per person, no voting for yourself, anonymous tally. For small teams, a three-person judging panel beats a popular vote.
Do you need prizes for an office costume contest?
No, but they help turnout. Leave early on a Friday, a coffee card, and a traveling trophy cover it. Keep the budget under $25.
What if nobody at the office wants to dress up?
Keep it opt-in and give people an easy on-ramp. A 2-minute costume quiz that builds a costume from things at home removes the biggest excuse, which is not having an idea.
How do you include remote workers in a costume contest?
Photo parade in a shared thread, a 24-hour voting window for every timezone, winners announced on a video call, and the prize shipped by email.
Should an office costume contest be mandatory?
No. Voluntary contests with good categories get higher turnout than forced ones, and mandatory dress-up punishes tight budgets and real objections.
How many contest categories is too many?
Six is the ceiling and four or five is the sweet spot. Every category needs at least three real contenders or the win feels hollow.
What is the best way to announce contest winners?
At the all-hands or in the main team channel, one line per winner saying what they won and why. Copy the Slack announcement above and paste it as-is.
