okay, the girl that i'm going to prom with is wearing like a coral pink dress with a silver waist band. i want to match what she's wearing but not exactly. i already have my pants and my shoes. all i need is a vest and a shirt. i'm not wearing a tux. my pants are like a white/tan color and their skinny. i have a white pair of TOMS and a white skinny tie. what color should my vest and shit be? please help.
