Deviled Egg
There are plenty of devil costumes out there. But this is a funny spin on it, if you don’t mind dressing up as an egg. This is as simple as costumes get. Wear a white shirt with a yellow paper cut out glued to your stomach. Then put on a pair of devil horns you picked up on your way to the party. That’s all there is to being a Deviled Egg. Pitchfork is totally optional, but would add some humor.
