>>1520266A while ago, someone mentioned that all the girls with red skirts and darkgrey blazers (which is the inversion of the standard uniform) happened to be seniors. From that point on, I just sort of continued to do it that way just for the sake of changing as little of other people's creations.
This would be a good time to put an axe to that and standardize the uniforms if you or anyone else wants to throw their 2cents in
