I never liked the school uniform. It is not convenient and not beautiful. Moreover, I do not like to wear skirts, but only boys wore trousers. But in some schools and universities, it looks beautiful 
For me having a uniform it represent that you are student in that particular school and also helps determine that you are student because of your wearing and gives you the identity...but in other country they don't have uniform like USA and others but in our country we have it saw we just embrase it...
