I also didn't dress like that in school, but all it takes is one person to dress inappropriately to have the administration enforce a strict dress code. I don't have a problem with piercings for the most part, just as long as they are tasteful. It is just inappropriate for girls to show as much chest and butt as they do. Not to mention I don't want to see all these boxers and stuff... they make belts to solve that problem.
