I wish I could remember the specifics but my high school had an extremely ridiculous dress code policy at one point. Mostly targeting girls, of course, but also had weird shit like “no large/long coats.”
What I do remember perfectly though, is that a friend of mine and I, angrily pouring over the details of the stupid dress code, realized that capes were perfectly fine according to the code as written. So we both got huge capes and that was like a whole year of high school.
