The email said “costumes encouraged.” You saw it this morning. You have a 10 a.m. meeting.
Every costume here goes on top of what you’d normally wear to work, takes 15 minutes or less, and comes off in seconds if a client walks in. No masks, nothing scary, nothing HR will want to talk about.

1. Rosie the Riveter
The best office costume there is. Rosie works over almost any outfit, and everyone recognizes her.
How to do it: Chambray or denim shirt with sleeves rolled, a red bandana tied on top of your head and red lipstick. Flex for photos. About 5 minutes.
Worth buying: a red polka-dot bandana.
2. Cat
Ears and a little eyeliner, and you’re a cat. It works with almost any dark work outfit.
How to do it: Black top or dress, cat ears and eyeliner whiskers. Skip the tail if you’ll be sitting all day. About 5 minutes.
Worth buying: a cat ears headband.
3. Witch
A black outfit plus a hat is a witch. Take the hat off for meetings.
How to do it: Black dress or black top and pants, a pointed hat and a dark lipstick. Bring the office broom if there is one. About 5 minutes.
Worth buying: a witch hat with a wired brim.
4. Mad Scientist
Perfect for the person in IT, finance or R&D. A lab coat turns any outfit into a mad scientist.
How to do it: White lab coat or white button-down, goggles on your head, and messy hair. Carry a coffee mug labeled “Experiment #13.” About 10 minutes.
Worth buying: a cheap white lab coat.
5. Cowboy
Casual Friday energy. A cowboy is a plaid shirt, jeans and a hat.
How to do it: Plaid shirt, jeans, boots and a cowboy hat. A bandana at the neck if your office is relaxed. About 10 minutes.
Worth buying: a classic cowboy hat.
6. Hippie
Comfortable enough to sit in all day. A hippie is a headband and round sunglasses.
How to do it: Flowy top, jeans, a headband across the forehead, round tinted glasses and a peace sign necklace. About 10 minutes.
Worth buying: a hippie headband set.
7. 80s Workout Instructor
Funny, colorful and great for a team photo. The 80s aerobics look fits over leggings or joggers.
How to do it: Neon top, leggings or joggers, a sweatband, leg warmers and a side ponytail. Stretch dramatically before meetings. About 10 minutes.
Worth buying: neon leg warmers.
8. Farmer
Friendly, easy and very office-appropriate. A farmer is flannel and a straw hat.
How to do it: Flannel or chambray shirt, jeans, a straw hat and a bandana in the back pocket. Bring a stuffed chicken to your desk. About 10 minutes.
Worth buying: a straw farmer hat.
9. Ghost (Office Edition)
A sheet ghost with a twist: you’re the ghost of meetings past. Wear the sheet for photos only.
How to do it: Bring a white flat sheet with eye holes for the costume contest, and pin a name badge to it that says “Boo, Accounts Payable.” About 10 minutes.
Worth buying: round novelty sunglasses.
