I work in the land of pencil skirts, heels, suits and Gucci-bit loafers. It's a pretty bland landscape as it relates to dress, particularly for San Francisco, however I suppose typical for the industry. Many are health freaks who seem to have an endless supply of green juice, have ditched their Rolex's for UP bands and have their yoga instructors come into the office for a little afternoon namaste. As of late, several of the gents have ditched their loafers their wives and girlfriends likely spent 5 hours selecting at Neiman's, for sneakers. I'm into it.
This seems to be a trend across the world. See more here.
