I pretty much wear whatever I want; so does my colleague Cs, a girl with a, uhm, cutely quirky style.
I can think of only two items I wouldnt ever wear to work: these black goth trousers with flares that have a bunch of metal stufflets in it and a chain-thing going around; and these sorta gold-coloured trousers with a kind of lightblue embroidery in it
(Mind you, I dont think Ive ever worn the latter, period, more than urr, two or three times.)
The techie guy just wears jeans and some kind of non-descript sweater or t-shirt. The office manager type person looks regular-pretty in an unconspicuous way.
Mind you, its really just the four/five of us in our program, anyway. I gotta say, the rest of the floor is another program, and the guys there mostly just wear the pants and shirt thing. No ties, but also only rarely jeans, I think. Women's got a little more leeway.
All depends on the culture of your office/program/etc I guess. We dont do any 'external' work, dont meet clients or the like, plus, we're basically friends anyway, so.. yeah, whatever.
When I have to travel to a meeting or a presentation we organise or the like, I still dont wear a tie and only sometimes a jacket, but I do wear a proper shirt and pants, not jeans or the like. Although again, even when we meet at the London office, its not like anyone cares.. its NGO culture. Well, European NGO culture I guess, I hear that in the New York office theyre pretty corporate in all kinds of way.
Only if you have to actually give a presentation at a launch or a conference or the like its different of course - but - not my job.
But yeah, I mean - you should hear what we chat about, for example. We're well aware that, the way we carry around, if we'd a worked in America we'd all so be fired
