Like everyone else......

Hi! Like everyone else, I have the same question: what to do with my hair for prom?? I have shoulder length (or a little bit longer) wavy hair in long layers. Last year for Prom, my hair was put up high on my head with a ton of curls. I know I definetly want an Up-do, one of the many reasons being because it`s so hot in the building that`s hosting our prom. Any ideas would be appreciated, thanks Bethy :)
