Totally agree with blueemerald. I'm quite happy for teachers to have a reasonable dress code, which can be enforced behind the scenes if neccessary - but there's absolutely no way they should be publicly treated as if they are on the same level as a student.
Funnily enough, DD would agree with bossboggle (in DD's words "it's not fair, they're no better than us - if we have to wear a uniform, so should they") and it's precisely that kind of attitude that is showing signs of hampering her learning and that I'm trying to nip in the bud.
I'd go as far as saying that teachers being treated like idiots who can't be trusted to dress themselves professionally, and have to be prescribed a uniform, would actively put me off applying to a school.
