Ive noticed this a lot that Chinese loves to wear something extremely short and above the thighs. For F sake, ive seen a standard 3 kid, wearing like that and the parents buat bodoh. Training the kid since small to wear like that? So in this case, i wont be surprised. What the school did was right as its tto teach the student on how to properly dress as a student, not as a slut. Its a charity event and not a striptease show. Why not go nude then since loves to show a lot of flesh to the public? Common sense, is something some people will never have till the end of the world.

for those who wants to wear according to their religions. go ahead too. dun jelly other ppl allow be pretty.
