Gakuen MLP

I got bored again.
I was looking a Hetalia Gakuen cosplay on bing (the safety was on thank god o_o) and I just got this idea after looking at the girl's outfits. Quick question why are girl's outfits red? I like it. :3
I already had this uniform base and I just killed another 3 hours between craddle and grave editing. I still reget the background. My eyes!!!
