Where can I find great prom hairdo ideas?

I am trying to find a really great prom hairdo. I want loose curls but I just can't seem to find the right picture of what I want. My hair is pretty long, and my cousin(my hairdresser) says to have a picture of what I want to give the person who does my hair the day of prom. If anyone had any good pics or web site ideas...please let me know! Thanks
