Dress code at school

So I'm wearing a dress today, everything is covered up. Dress down to my knees, the girls are tucked away. I think it is so stupid, I literally just had my counselor ask me if I was aware that I was in violation of the dress code. She asked me if I had a jacket and I said yeah. I had to put it on, she told me that she would send an email to all of my teachers saying that I must keep the jacket on due to the fact that I'm out of "dress code" minutes before that I had walked past my principle and the only thing said was, male sure u put on your I'd badge before u go anywhere else ok. That's it, but my counselor who I was trying to ask about talking to a navy recruiter. Nope she was worried about me SEDUCEING SOMEONE WITH MY SHOULDERS!!
