I think a vintage rock and roll/hipsterish style is hot on every girl, but no one does it so you can try that0

You have to figure this out for yourself.
Find a picture of a girl with the clothing you like and try to dress like her. Then your own style based on that will develop through time.
Anything anyone tells you to buy won't actually be what you are. O. o0
