Where can I find a quality women's corduroy blazer in San Fran?

I've got an unexpected day free in San Francisco tomorrow and I'd like to do some shopping. One thing I haven't been able to find back home in Sydney is a nice corduroy women's blazer. I had one years ago in a lovely dusty pink and I wore it til it fell apart. Anybody know if they're "in" this spring and where I can find one in the city? (Colour doesn't really matter.)
