For a man who so often appears near-naked on the pages of women's magazines and stages around the world, it might seem a bit contradictory to refer to Maroon 5's Adam Levine as a style icon.

However, the inked up pop star, who turns 35 today, has shed his reputation as an uninspiring dresser, and emerged in recent times as a champion of everything from distressed denim to sophisticated tailoring.

Regardless of how you feel about Levine's music, his style credentials are harder to dismiss. While his look is sort of "average Joe," with white crew necks and slouchy band tees forming the bulk of his wardrobe, it's his ability to add subtle touches, like a shawl collared cardigan or killer pair of boots, that marks him out as a real power player.

But it's when he's in full performer mode that he looks at his most sartorially accomplished, proving that the key to feeling comfortable and looking your best is to fall back on your favorite T-shirt, even if it is a bit stained.
