I'm as lucky as Peter. I have never seen a school uniform in real life, ever. Only on televizzle and stuff.
The thing is, that the 'preppy' style fashion is getting more and more popular here, and people go out and buy fake school uniforms (with made up names on badges, etc) and wear them, thinking they're the shit.
Strange what happens when you're free to wear whatever.
At my school it is quite separated. People wear what they want, and you can clearly see who is what, and who to stay well away from. If our teachers want us to stfu, they tell us so.
I've never heard -that- much about discipline in neither school nor college here. Our school system works pretty well I think, and I'd be very surprised to see school uniforms in public schools and colleges here, only in the very posh private schools.
