No dress code at my high school. I mean, at all. I've seen girls bare their midriffs and wear booty shorts and not get called out for it. I've seen guys with hair longer than mine (that's saying something, at the length it is now) and girls with pink hair. And people with piercings all over. Yeah. It's all cool with my school, though. I think I got off easy compared to most of you.
In my old Catholic school, the girls had to wear jumpers when we were little and then polo shirts and kilts when we were older. Of course we had to have our shirts tucked in, no dark nail polish, wear belts if you wore pants, blah blah blah. But I left my shirt untucked for half of seventh grade and all of eighth grade and no one really noticed. I also rolled my skirt up a lot because it was so long and it looked awful. But nope, I never got in trouble for that, either. :P
