Halloween is just around the corner, and if you’re one of the lucky people who get to celebrate the day with a costume at work, now’s the time to start planning your look. Most employers allow a lot of latitude in costume choice, as long as you follow a few widely accepted rules: Nothing revealing, nothing offensive and nothing that will interfere with your ability to do your job. With that in mind, here are ten great office-friendly costume ideas sure to be a hit.

Rosie the Riveter
Get this 40s icon look wearing a denim shirt with sleeves rolled to the elbow, a colorful red bandana and some awesome red lipstick. Wear faded jeans with folded cuffs.

Where’s Waldo
Wear a long-sleeved white tee; add horizontal red stripes to it with a marker or tape. Add a knit cap, big glasses and a few explorer accessories like binoculars, camera and backpack.

Kermit the Frog
Make frogeyes with two ping-pong balls and glue them on barrettes for your hair. Wear a green t-shirt and wear a collar of green felt triangles attached to a piece of string to tie around your neck.

Mad Scientist
Wear a lab coat over a mismatched outfit. Add big glasses and a clipboard—spray your hair into a wild mess if you dare. Carry around a glass of green or blue liquid.

Gypsy
Wear a long skirt, breezy white blouse or tunic, lots of bead necklaces, gold hoop earrings and a brightly colored scarf around your hair. Carry Tarot cards if you have them.

The Pink Slip
Get an oversized ladies’ slip and dye it pink. Wear it over a black turtleneck and leggings. Carry a clipboard with your coworker’s names written it.

Celebrity Chef
Dress like Paula Dean or Guy Fieri or any of your favorite TV chefs. Wear an apron and carry a wooden spoon. Bring some homemade goodies for trick-or-treating coworkers.

Veterinarian
You can usually find cheap scrubs at a thrift shop or discount store. Wear old tennis shoes with a few drops of red food coloring to simulate blood. Bring a few stuffed animals for your desk.

Starbucks Latte
Wear a tan T-shirt dress with tan tights or leggings. Wrap a white feather boa around your neck to represent foam and stick an enlarged copy of the Starbucks logo to the front of your dress.

Hippie
Get out your tie-dyed shirts and bell-bottom jeans. Floppy hats, love beads, oversized sunglasses complete the look. Flash the peace sign.

Whatever you choose, keep it tasteful—and don’t forget trick-or-treat goodies for your desk!
