When Emma Watson made her big screen debut in 2001 as the quick-witted and overachieving Hermione Granger in "Harry Potter and the Sorcerer's Stone," she immediately captured our hearts. But it would take years (and some help from the fashion houses of Alexander McQueen, Valentino and Chanel) for the starlet to become a red carpet pro.

Continuing to play the role of Granger in the "Harry Potter" film series, Watson enrolled at Brown University and transitioned into the world of modeling as the face of Burberry. However, her most shocking decision to date happened back in August 2010 when she chopped her long locks into a Mia Farrow-inspired pixie cut. And with a Vogue cover, Lancome contract and more movies under her belt, we can't wait to see what magic Watson stirs up next, on and off screen.

In celebration of Watson's 22th birthday on April 15th, we're taking a look back at the actress' style. Vote on all of her looks in the slideshow.

And don't miss Watson's experiment with hair extensions and tattoos.
