What does business casual mean to you?

I’ve been working various temp jobs in a very easy going city (San Francisco). For the two most recent jobs, they’ve listed “Business Casual Attire” but I’ve shown up so over dressed!

To me, business casual is black pants, a black tank top/long sleeve, cardigan/sweater, and black shoes. But jeans are completely acceptable at a lot of places around here. Even sneakers are okay as long as they’re not nasty!

Obviously for first days, I always wear AT LEAST black pants and a sweater or a sweater dress… not too dressy but not casual either. But I’m curious as to what you guys think Business Casual means in 2010/2011??
