Think globally, buy locally
Wouldn't have expected this sentiment from someone with a Bush/Cheney avatar. Not criticizing, just commenting. In my experience -- having lived in the Mountain West, Upper Midwest, Texas, DC and NYC-- as one moves westward in the U.S. there is a concomitant lessening of respect for "institutions", be it government, universities or even social conventions (not necessarily manners, but conventions that don't seem particularly practical). I find this includes dress: as one moves from east to west, there is less interest in communicating things like social status and formality with clothing. Even macho guys in NYC will take great pride and care in their appearance, whereas even non-macho guys in the West would find such concerns to be irrelevant (not to mention effeminate). Thus, I find that clothing is by far the most casual in the Pacific Northwest, where leather soled shoes and shirts with collars are looked at as fairly pretty impractical and formal. NYC is bar none the most clothing conscious. DC and Texas were about the same, but in DC it was a professional and decidedly non-stylish look (the ubiquitous gray ill-fitting suit) at was necessary for professional reasons, whereas in Texas it was more peacocky and done to insinuate financial well being and importance. What little time I spent in SF, it seemed to be pretty Banana Republicy, while thinking that was well-dressed. Then there are the stereotypes -- NYC wears a lot of black (true), Texas wore bright colors (somewhat true, but a lot of black as well), DC dresses conservatively (true), Midwesterners are douty (truish). I think there are differences, albeit slight ones. Good thing for diversity of opinion and lifestyles though, so people can pick and choose where they'd like to be and with whom they'd like to be.
