This is the last thing i'm going to say about this because I did hijack the thread and I apologize, but it is our middle school's policy and our principal did make that request of our teams. It wasn't some big issue within our school. She asked, coaches agreed, girls agreed, and that was the end. I really don't appreciate being made out like I made up the story. My main point was essentially it's not entirely unheard of to have an undergarment dress code in my area, whether or not you agree with it. Sorry to anyone I may have offended.
