pretty hairstyle for formal

Mmkayy. Hi people!
Anyways I'm new... and im looking for something that would work with my failure of hair, and look pretty for my 8th grade formal. So. My hair is pretty long, about 12 inchers from the end of my ponytail, layered, semi wavy/frizzy, and almost impossible to control. It's also kinda sorta veryyy thick.
Anyways, i want something pretty, but not overly old fashioned. I don't have a straightner...TT_TT but i do have a blow drier and stuff. Not that my hair actually works with it but still. thanksss xoxoxo
