Dressing up for Halloween as an adult usually means choosing between a sexified version of a cute animal and something a grandparent might wear while taking the kids trick or treating. That can make picking a costume for a work party like walking through a minefield. You don’t want to end up with something NSFW, but you still want to look cute, professional, and like you put in the effort.
The trick is to look for something modest yet relevant or timeless. For example, these costumes are some of the best adult Halloween costumes for office parties that’ll get you some laughs, maybe an award or two, and they will undoubtedly have you in the spirit of things without making you or anyone uncomfortable. We’ve also got other round-ups on SPY that include Halloween options for work, like best pop culture Halloween costumes and superhero costumes, as well as funny Halloween costumes for couples, and family costumes that allow you to enjoy the holiday with your spouse and/or children.

11. Super Mario
It’s Super Mario. Need we say more? Of course, it’s a work-appropriate Halloween costume, but this one is also great because, depending on what you have at home (like overalls), you might only need to buy Mario’s signature red M cap.

12. Yourself on Zoom
If you work in a white-collar job, then you’ve spent the last year-plus on Zoom or another video conferencing service. Going as yourself on Zoom is a bit of a lazy costume, but we’d be willing to bet it will warrant a few chuckles. Even when we’re in person at the office, we still won’t be able to escape Zoom. Just cut a rectangular frame out of the cardboard and use some string or elastic to make a hat. Alternatively, carry the frame in front of your face whenever you’re talking to anyone.

15. Hand sanitizer
The COVID-19 pandemic, naturally, is an unavoidable topic in 2021. But rather than overshoot by going as the virus itself, which would not be a good look (remember, the death toll is still on the rise), go as a bottle of hand sanitizer. It’s a lot less glib and gives you a chance to promote just how useful you are.
