Justin Bieber's Style Evolution (PHOTOS)

Justin Bieber has come a long way from sporting wide-brim baseball caps and plain T-shirts while belting out cover songs on YouTube. Since breaking into the music scene in 2009, the Canadian-born pop star has transitioned into fitted cardigans, leather jackets, skinny jeans and neon-colored sneakers that look as though he has been playing dress up in mentor Usher's closet. And while Bieber finally cut ties (pun intended) with his famous bowl haircut, I have a feeling that his b-boy style isn't changing anytime soon.

As the "Never Say Never" singer celebrates his 18th birthday this Thursday (March 1st), we take a look back to see how his style has evolved over the years. One thing's for sure: The Biebs sure does love wearing the color purple. Vote on all his looks in the slideshow below.
