You may just have to wait until college to wear what you want, like I did.
I feel that if wearing your scarf is a part of your faith and you still want to stick to that faith, get a few kinds that you really like and rock it! I've seen some gorgeous ones as well as girls who make awesome outfits with them.
As for clothing, throughout high school, I wore my vintage Levi's "mom jeans" with Dr. Martens, a tank top and an open oversized flannel with my hair in a messy bun. I was in a fortunate time where the grunge look was coming back and I was considered stylish, but the reality was that I couldn't really leave the house in much else without being sent back to my room to change. So I just took it in, did my fashion research, did the best with what I had, and put my paisley hippie dresses and Bohemian jumpsuits in my bag before moving into my college dorm. When I'm in college, I wear what I want--I don't like booty shorts and bra-tops either, but am really into 60's/70's hippie clothing. When visiting the parents, I dress more conservatively, just to respect their comfort zone--they are helping me to pay for college, after all. And when I'm truly out on my own, I can do whatever.
