My choice of clothing is pretty much the same as it was when I was attending college: a t-shirt and jeans or shorts in the summer, and jeans plus a sweater or sweatshirt in the winter. I do have some t-shirts I won't wear to work because of what they say on them, but this doesn't affect many of my shirts--I still wear 'Johnny the Homicidal Maniac' to work, for example.

Perhaps twice a week I'll wear a shirt which isn't a t-shirt or a sweatshirt (women's clothing doesn't fit into the same neat categories that men's does), and about once a month I'll wear a dress or skirt if I feel like it. I actually dress up less for work than I sometimes did for school, because at school I'd sometimes show up in evening dresses if I was completely bored. Although I'm pretty sure my boss wouldn't say anything if I were to dress like that, I haven't had the urge to test that.
