The party at Wellesley College made famous by Rolling Stone Magazine held every spring.
Originally meant as a celebration of everything queer and as a queer prom. It's most well known for it's "creative black tie" attire that requires drag from any men attending (guests are required to have a Wellesley escort to maintain safety) and generally lingerie from women (genitalia is not suppose to be exposed). It rocks.
