DANCE HAIR HELP!

Hey everybody! I have a dance coming up (very soon!), so I need some HAIR HELP! I have brown, wavy, thick hair that is about 1-2 inches past my shoulder. I really want to look good! It`s a fairly casual dance (no long ball gowns) and the them is CARRIBEAN. My outfit is pretty Carribean already, so my hair doesn`t have to be. Originally, i was going to iron my hair COMPLETELY STRAIGHT (it`s really easy) but then I realized that probably half of the other girls will do the same thing, so I didn`t really want to look like a clone of everyone. Now, I`m stuck for ideas. I want it to look naturally pretty and I want to wear it down ( I`ll be putting a flower in my hair) DOES ANYONE HAVE ANY IDEAS ABOUT HOW i SHOULD DO MY HAIR!!!!!!!?????? It would really help me out if you did have some ideas! I would be soooooooo thankful! Thanks, Arianna (p.s.- I was thinking that maybe curling just the ends might look good, but I`m not sure; or maybe scrunching my hair?! I REALLY NEED YOUR HELP!)
