For high school uniforms, they should be basic, and nothing too revealing. An ideal uniform for me is a full shell with no cut-out areas, a pleated skirt (knife-pleat or box pleat), and a full bodysuit (with snap crotch). I also think every high school cheerleader should wear pantyhose as well. I always wear Sheer Energy nude or suntan color nylons with my uniform. It makes our legs look so much more even-toned and attractive. They are especially nice during football season for cooler nights.
I have no problem with booty shorts. In fact, I think bodysuits should be made with either the standard bottom or the booty-short bottom, such as this one:

I'm thinking about buying that bodysuit for next season. It's a custom-made one that I wish would be readily available like regular bodysuits are.
