I'm thinking of my own high school, 60's era, where the dress code for the upper grades was strictly enforced as coat and tie for the males. That got contentious for a friend of mine and he was sent home for being underdressed, some technicality as I recall. So the next day he showed up for class in a full tuxedo with cummerbund and pumps and the whole works- and got thrown out again. Really there's no pleasing some people.
