How can i make up my own style & be more confident? d:?

I'm a 15 y/o girl, and I think that the most important thing is being happy with your body. Almost all clothes look good on a body that is fit and healthy. After that, your options are not as limited and you can wear whatever the heck you want. I wouldn't bother going for a "look" but just wearing what you want. Obviously avoid things that make you look bad, but other than that... the key is loving your body, which is what I discovered this year. Confidence doesn't come from wearing a certain type of clothing to create an impression on people, but from keeping your body at its prime (by eating right, exercising a lot) and knowing that you got the stuff. YOU wear the clothes, the clothes don't wear you.
