Justin Bieber has undergone a style revolution over the past few years. Gone is the baby-faced boy with the mop top haircut (well, to be fair, he still has that baby face), but with his edgy new style and tattoos, the Biebs has certainly come a long way!
He has listed Kanye West and Usher as his style icons, crediting the latter for teaching him how to put stuff together and to accessorize appropriately, and lately we've noticed that Justin is super obsessed with hats! Whether he's on the red carpet or recording in the studio, you'll never see him without his most favorite pieces, including his signature snapback, wide-brim Panama hat or a beanie.
Judging by his latest Instagram pictures, Justin also seems to be taking a few style lessons from other stars, like when he rocked a backwards baseball cap with Calvin Klein underwear—an obvious throwback to Mark Wahlberg during his Marky Mark and the Funky Bunch days!
