Should I stay boyish or change a little?

Dress the way you like. I was the same when I was your age, I loved it. I know some people didn't think I was the prettiest girl but hey, I was happy. I eventually grew into my own style and now I love the way I dress. It's never anything more than just jeans and shirts, so I'm still a little tomboy but I throw a little girly girl in with jewerly and what not. You have to discover your own style, not follow the crowd. Besides, who wants to be just like everyone else? That's no fun at all.
