nwr: what do you wear to work?

I just got my first job as a full time teacher, which means that I need to dress like a full time teacher... but have no idea what that really means! I have clothes from my student teaching, but we were told that we had to dress nicer than the real teachers because we were younger (I was only 20 at the time) and also because we were representing our university and therefore had to look good and professional.

So, I went shopping today, but I feel like I have no idea what people wear out there in the 'real world' other than business suits (which obviously aren't appropriate for teachers) or like frumpy old lady mom clothes (which, as I'm only 22, really don't work for me!)
For my last job there really was no dress code - jeans, tshirts, flip flops, whatever.

So, anyway. It got me curious - what do young people wear to work? How many of you actually wear suits to work? If so, what is your job? If not, what is your job and what DO you wear? And what do young teachers wear to work so that they don't look frumpy but still don't look like their students? Where do you shop for these clothes?

I'm fascinated by the whole idea now
