Prom is the climax of the high school social scene in popular media. Movies, songs, etc., refer to prom constantly, but how does the prom experience differ for each gender?

Prom varies greatly in expense between the genders. Males traditionally rent a tux, drive to the dance and pay for dinner. Females are expected by most people to buy a new dress and do their makeup, nails, hair, etc. Obviously not all people follow these generalizations, but these expectations differ greatly.
