Christina Aguilera as a nurse
Ever since high school, Halloween is no longer a scary event, it's a trampy event. It's the one time of the year you can walk out of the house as slutty as you can get and no one giving you the dirty look. It's really not about the costume so much as it's about how little you can wear that still slightly resemble a costume. Paris' bunny is a case in point. Really, aside from the ears, what's really a bunny (as in baby rabbit) about that outfit?
I'm not judging though, cuz it's pretty fun to role play, especially in public. But I do miss the days of wearing an actual scary costume and having fun looking like hell.
