I don't see how ethnicity plays into this, however culture definitely does. I view SF as a middle ground for all types of people who buy and appreciate a certain type/brand of clothing aesthetic. My ethnicity doesn't play into anything SF-related because what I wear (and like to wear) have always been within the SF norm. Many people have significantly changed their look/wardrobe after coming unto SF, as this is a culture in its own right. Personally, other than learning about certain brands that I hadn't heard about, I haven't changed much in the way I look or dress. However, I work in a corporate environment. We have a pretty standard dress code which has created a common ground for all to follow, thus eliminating most cultural and ethnic influences.
