14. Big Sean
We've been spotting Big Sean in wavy clothing all year long, so it's no surprise that the G.O.O.D. Music member is one of 2012's most stylish. Back in November, he told us that he doesn't follow any strict guide to dressing, and dresses however he's feeling. Well if that means rocking designer pieces without losing his preference for a more athletically-inclined look, then he's setting one hell of a code.
