I dressed up as Roxie Hart from Chicago. Super-short silver dress with 6-inch fringe, blonde wig, tons of makeup, and 3-inch heels. I actually came in second in the costume contest! I lost to a woman in an inflatable pumpkin suit, but I still got a $25 gift certificate.
In my quad, we also had a female vampire, Norman Bates from Psycho, and one of the monks from Monty Python and the Holy Grail. We were the only quad that really got into Halloween this year. It was kind of a disappointment.
