Make up or... NO?

Prom is next Thursday and I need your help, Crazers! My prom outfit will be a white gown with sparkles at the trim of the dress and I'll be wearing a glass (white transparent) high heel (AKA slipper lol) to pair up with it. I don't know how to do my hair... Please help. Also, I don't know if I should put on makeup or not. If so, how much...? Life Is soooo confusing!
