What hairstyle should i do?

Okay I am going to a school end of the year party where you get certificate of completion and all the great stuff. Then after wards later in the day there's a banquet. I'd appreciate if you guys would throw in some ideas for a hairstyle for me. I have dirty blonde hair that comes down to my shoulders and bangs that fall over my forehead (but sometimes i brush them aside) I just want to know what an awesome hairstyle i should do for both occasions. thanks! :D
