What kind of hair should I do for graduation?

I have a medium length layered straight hair. Well

my hair`s only straight when it brush it but if I don`t

brush it then it`s a bit wavy. Anyways, my dress is

really rich blue and it`s pretty long. It`s a two piece

with a tank top for the top and like I said, the

dress is pretty long.

Do you guys have any ideas on how to wear my

hair? I`m going to get it at a salon but I still need

ideas.
