Sure, the gentleman is known as the Sartorialist, but that is more for Scott Schuman's eye for fashion and well-dressed folk on the streets of cities like New York, Paris, Milan, Stockholm, and London. But do not overlook the man's own personal sartorial style. Scott's cool. And the second shot below (of Mr. George Cortina, professional stylist) is also from Sart's blog- showing you he really practices what he preaches.
And he's right on.
UPDATE: Also found Mr. Cortina (here with Mr. Hamish Bowles- also looking quite dapper) from another of Sart's postings- this time courtesy of Mr. Schuman's blog at style.com
