The high school stories sound like everyday stuff in half the high schools across the country that have dress codes. I remember the whole us against the teachers thing in high school, girls pushing the lines of short shorts/skirts and guy with the various innuendo shirts. Girls were known to wear skirts that were acceptable and then roll them up to a shorter length once at school. There would usually be a few crackdowns through out the year and it was stated in the rule book at my high school that the first offense you would be given the option to change the offending garment, be it clothes in the car or calling a parent to bring you a replacement, and any refusal would result in being sent home.
