Uh, yeah, the cheerleaders were all dressed like this today. I have no idea.
edit: The general consensus seems to be that since it was a Maize Out for this game, and their usual uniforms are mainly white, they borrowed these outfits from somewhere (maybe the actual golf team?) so that they would be wearing yellow along with everyone else. The problem, of course, is that these are pale yellow and not maize at all. Plus the cheerleaders are on the field, not in the crowd where the Maize Out actually matters. Nice gesture, executed wrong.
