22. Andy Cohen, "Watch What Happens: Live"

So you probably only know Cohen as the jolly, quippy buffer between table-flipping housewives. But, the Bravo ec has etched out another title in our heads as one of the most dapper dudes on late night TV—a space that, let's be straight, could use a big ole upgrade. Whether he's shooting the shit with Tina Fey or an ousted reality star on his chat show, "Watch What Happens: Live," he brings his A-Game with slimmed-down suits—more often than not from Ralph Lauren Black Label—spot-on pattern-mixings, and, on nights when he's thrown back one too many Maker's, a deftly flown-open collar that's every bit tasteful.—A.R.
