at my school you can wear anything, as long as the it doesn't show your belly button. But nobody listens. We have a gym uniform black shorts and white t shirt, they both have the school logo and a place for you name. If your name is not there you lose 5 percent on you report card. If you were someone elses uniform (eeww) you lose 10 percent. If you forget it you lose 4 percent, but if you wear another short and t shirt you only lose 2 percent. I memerized all this, and also haven't lost marks because I leave my uniform in my locker and have not washed it since i bought it at the beginning of school.
