Punk Rock Prom Queen:
Wear wide legged pants, like blue jeans, preferably dragging on the ground. Add a simple black T-shirt, or your choice of shirts with or without offensive and/or morbid slogans and messages.
With a few nail-studded bits of leather jewelry, you can top it off with a thorny tiara and a sash that reads "punk rawk prom queen."
You may add an anarchy symbol if you wish. I know that's not how you spell rock, and it does annoy me, but one of my friends did this and it was hilarious.
Thanks to an anonymous submitter for this fun idea!
