Well, not exactly SF, but the northern Bay Area is where I ran into casual coolness. This proves that you don’t have to be trendy or over-the-top with fashion to be stylish. I always think that style comes from within and it truly shows when someone is trying too hard which usually results in uber fashion faux paus-es. Even with a simple t-shirt and jeans, accessories with character can accentuate low-key into a dapper look.
