I wore a uniform in school (in the UK) until the age of 16, and now I teach in schools with no uniform and I do see a (albeit small) difference.
I really liked the uniform when I was at school, because I never had particularly nice clothes/trainers etc and the uniform was a bit of protection from being laughed at on that score.

So the point I'm making is, maybe uniforms have a weird social effect on some people?
I think it had the same effect as it did on you - making you feel different - but in a positive way. In school I knew what I was doing, and the uniform kind of reflected that. Out of it I was a mess, and I never felt comfortable on non-uniform days. It also gave a nice feeling of distinction between school and free-time. I agree, however, that it does make kids more rebellious, since we had to show our personality in different ways (in my case that was multicoloured nail varnish and enough hippy jewellery to sink a battleship). We used to delight in the small ways we could undermine the uniform rules, like folding the bottom of our shirts over instead of tucking them in. One good point on that score though is that while we were taken up with petty stuff like that we weren't doing anything more serious.
At the schools I teach at now the kids can wear whatever they like, and that's great for showing their individuality. However, I think it takes something away from the discipline - the line between pupil and teacher is a little bit less concrete (especially in Finland, where we wore really casual stuff to teach in). I have also witnessed some pretty nasty clothes-focused bullying, though of course bullies will find anything to differentiate people and clothes are just an easy 'in'.
Ultimately, like everything in the education system, it works for some and not for others. Your experiences show that it really didn't work for you and that's sad, but I feel that it did work for me. As one of three kids I think my Mum was thankful for it as well, since it was hand-me-down heaven and a lot less washing
EDIT: I forgot to mention that working in a non-uniform school does create some hilarious situations, like when half my class started copying the 'cool girl' who dresses like a hooker from the 80s. Or the time where one of the little shi.... *ahem* more difficult students came in wearing the same top as me and spent the whole two hour lesson scowling while the others ripped the piss. MWAH HA HA petty revenge is sweet.
