If you've ever spotted a pic of Justin Bieber and instantly felt the urge to yell "Get yourself a belt, kid!" you're definitely not alone. The 21-year-old superstar's got a thing for rocking baggy looks, but in GQ's March issue [1], he's finally found himself a tailor. And — get this — he doesn't look half bad.

On the cover, Justin can be seen in a spotted shirt and plaid jacket, paired with a variety of statement rings (the rock star look, some might call it). In other photos, he's all about the mismatched set and even wears a bow tie (aka the coolest wedding date outfit ever). Overall, we've gathered there's a real lesson to be learned here: the wonders of a great fit. Please, please take this into consideration, Bieber?

Keep scrolling to see the star appearing to be all grown up — and ugh, fine, there's a shirtless [2] shot included, too. Then head over to GQ's site [3] for more snaps of Justin in adult clothes and channeling his inner James Dean.
