WHO: Sean Sullivan (@impossiblecool), Founder and Blogger of The Impossible Cool
WHY YOU SHOULD FOLLOW: You may remember Sean Sullivan from our "Iconic Movie In Six Frames" feature. If not, you probably know him from all of the other cool shit he's associated with. The New York-based arbiter of style keeps us inspired with his twitpics of stylish gents, and sometimes women—word to Ms. Hepburn. If he's not spewing out sartorial images, he's letting us in on his day-to-day tasks such as shooting with Jake Davis or attending the numerous fashion events.
