Help! What Hairstyle Do You Like Best, Curly, Wavy or Straight?

i'm 15 and i have dark brown shoulder/elbow length hair.
it's naturally curly but what do you think looks best?

Suggestion:

I like them all.
All are really pretty.

You can wear curly hair if you have a plain outfit.
Straight if you have a dressy outfit.
Wavy if you want to go more natural.
