YABU - Can't see that there is anything to be proud of myself.
I currently teach at a college, where there is no uniform and teachers are all on first named terms. Before that, I taught in a school with sixth form, where even the sixth formers wore uniform and called me miss.
Although this is anecdotal evidence, but I can't say that uniform or otherwise changes much. I think it reflects the culture of the school - the sixth form was much stricter in its culture, but I would say that the uniform reflects that rather than creates it.
And finally, when I taught at school I still had the same issues as I have now at college - at school, most students abided by the rules, but a few liked to push it. Now, I'm at college, all we have is a decency policy, and again most abide by the rules but there's still a few that like to push it and wear overtly sexual / inappropriate clothing. Same conversations, just slightly different context.
And no, teaching at a non uniformed college is not something I am particularly proud of, or feel any particular emotion towards full stop really. Quite an odd concept really.
