It was this very type of issue that prompted mandatory uniforms. Sponge Bob and Victoria came to class everyday to audit the courses but never paid tuition
Just having a "presentable" dress code wasn't good enough. Gals insisting being braless in a predominantly male classroom is her right but, having men say something isn't. Men AND women showing off rear clevage...umm, eww! These things are not appropriate in the classroom. The sexual harassment risk skyrockets.
