Should we wear school uniforms?

Nowadays there are a lot of countries where it's compulsory to wear school unifor specially England.
In the past it was compulsory for people wear a unifor, but nowadays in the public schools they wear a uniform and in the state schools they don't.

The advantatges of a school uniform is that there is less discrimination and everyboody is the same because everybody wear the same uniform.
Another advantatge specially for girls is that if you wear a uniform you don't have to think about clothes and in this way you don't waste time.

The disadvantatge is that you are like everybody else and, therefore, you don't express your personality.

In my opinion, I think that it's good wear a uniform because people don't discrimination and normally they have a similar thinking on the contrary, I believe that these people don't hve a personality because nobody stands out from others.
