I live in California and work with someone who recently moved here from Baltimore. He's kind of an older gen-X guy, and he likes to go to thrift stores, buy old suits for < $10 and wear them ironically, like with dress shoes but ankle-length white socks and the sleeves pushed up, and the front end of the tie shorter than the back end.

Every few months, a manager will pull him aside and say in a trying-to-be-friendly way, "You know, you really don't have to wear a suit around here." To which he'll respond, "Yeah, I know, it's just my thing, man." And then there manager will stare at him a little harder and say something along the lines of, "No, I mean you really don't have to wear a suit around here." Eventually the manager gives up and writes him off as an incorrigible free spirit.

TL;DR The West Coast is a place where you can wear whatever you want to work, as long as it's a Hawaiian shirt.
