It's actually very good of you to bring up this subject.....most teenagers wouldn't bother. I just suggest you dress modestly. There is no need for you to 'cover' up; however if you don't want them to stare, just avoid wearing 'revealing' clothes. So jeans and a t-shirt are fine for example. Belly buttons out and tank tops (where half of your undergarments can be seen) or 'see through' stuff are no no's. No hot pants, or short skirts too.

Just a suggestion. :)
