Yo, there's a Muslim society in Malaysia addressing our juniors school uniform as sexy. As a student years ago, I'm quite agree with their statement. White baju kurung is extremely quite sexy.
There's a story I heard about this sexy uniform when I was in school. This is about a boy, stalking a girl, then the boy later found out that the girl always wearing the same, umm, what we called that eh? It is like a singlet, but design specifically for girls. Okey, then this boy found out that this girl is always wearing the same 'singlet' everyday! Then, acting like a man, this boy, collect some money from his dudes. He went to a shop, put a China wall bricks on his face, buy a this nice 'singlet', wrapped it, and donate it to the girl he always eyed. So, the girl here was sexually harassed while the boy got his chance to become a gentleman. The point here is, white baju kurung is too transparent while the boys got attracted and become wild, uncontrollable.
So, a call to review our school uniform policy is understandable. It is to protect our girl from being harassed, worst they might be molested. Then, for those who get easily bitchy about this issue should think again. They(the Muslim society) are really working to protect women, not to lock their freedom.
