Charlie Siem is, literally, the very model of a modern major violin star. At just 25, he's already appeared on the world's great concert stages, as well as the pages of Italian Men's Vogue magazine. He's also the 2011 spokesman for Dunhill, the men's fashion house. For his Tiny Desk Concert appearance, you could say Siem dressed "casual, but with an understated elegance," right down to his left-hand pinky, with its pink-painted fingernail.
