In 2009, Justin Bieber released his debut album, My World. He was only 15 years old, and at the time, he still wore purple hoodies and had his signature "Bieber sweep" hair. But it's a different ball game now. Since then, the Biebs has collected dozens more awards, topped the charts with a few new hits, and has even more Beliebers following his every move. And in case you haven't noticed, his personal style has gone through its own period of development and progress, too.
These days, the pop singer is all about leather—leather shirts, leather tank tops, and leather sweatpants. But of course, he didn't just jump from point A to point Z overnight. Check out the rest of the trends and looks he's tried throughout the years in The Stages of Justin Bieber's Style.
