High school clothing

I know some of you have kids in high school or are otherwise familiar with kids that age at school.

Since it's been a *long* time since I was in high school, I figured I'd ask for some input as to what's acceptable wear at school. I'm considering having a character in high school wearing some very skimpy, tight shorts or pant (if the shorts aren't acceptable). Just not sure if that'd violate the dress code of most high schools.

Whatever the character winds up in, it's supposed to be skirting the edges of acceptable, and worn to make a point
