High School Help! I'm switching schools!?

I plan on switching schools junior year. I'm kinda in the popular group like I hang out with all the white preppy kids. The school that I plan on going to is super preppy I'm talking the kids there act like the girls from mean girls. They judge what you have on and you better not be wearing uspa. I'm actually top dawg at my old school and dress really nice (polos, guy harveys, cardigans) and people say im funny. I'm just worried that nobody at ga will like me. I know some people there though. Did you think I'll fit in?
