As ideas go, this one is pretty simple. Man wanders around Manhattan with a camera. Spots someone whose outfit he likes. Asks if he can take a picture. Goes home and posts it on his blog. But the man in question is Scott Schuman, who had 15 years’ experience working at the high-fashion end of the clothing industry before starting The Sartorialist. He’s got a sharp eye for a good look, a gift for grabbing an on-the-hoof pic and an unwavering enthusiasm for people going the extra mile in the name of style. Minimalist it might be, but his site – a basic scroll of full-length street portraits, occasionally annotated with a brief note – is mesmeric and oddly beautiful. The site attracts more than 70,000 readers a day and has been named one of Time’s Top 100 Design Influences. So if you’re out and about and a guy called Scott asks to take your picture, just smile. You’re about to become a style icon.
