Newspaper style sections love to tout the return of natty dressing and mad men grooming, even if their subjects in question are all within a half-mile of the West Village. But it looks like San Francisco is really catching on. During a recent trip I saw less plaid, more Nudie and J. Lindeberg. And while I can’t exactly shout “trend!” I did spy two gentleman on market st. in the course of four blocks wearing designer pocket squares in the back pockets of white or gray denim. A cheeky play on hanky culture in 1970s Castro culture? I didn’t ask, but snapped this guy’s photo on the sly. I believe the pocket square is Paul Smith.
