You realize that by 'confiscating' your clothing, they are, in fact, committing a misdemeanor by 'Theft of Private Property'. Inform them of such the next time they do so, and if they become stupid, inform them that you will have your parents contact the School Board, the local Police Department, and the American Civil Liberties Union, and your parents will press charges.

I applaud you, lol thats probably the best thing to do in this scenario.

Anyhow, my school is pretty mediocre on the dress code, you can wear practically anything, and I usually slide past it. Girls cant wear skirts past their fingertips, and wear clothes with holes in em ect. Anyhow I always wear some slipknot shirts like "fuck it all" or w\e and no one says shit to me.
