Prom hair ideas. I have medium-long hair length and a sideswept bang. Thanks? By zara | October 7, 2009 - 7:23 am |October 7, 2009 What will you look like? I’m going to prom and I’m a junior. I need some do-able prom hair ideas for myself. I have black hair and I want something with gems or something cool. I can do curls or whatever, thanks.
