The annual Cannes Festival is one of the most important moments for a Hollywood star to make his or her film debut. Along with that comes the responsibility of looking good too.

For fans of Hermione-ehem-Emma Watson, you will not be disappointed with this former child star's development. From the awkward but brainy Hermione Granger to the fabulous fashion icon of the newest film entitled "The Bling Ring", Emma was the fashion darling at the premiere of the movie during the Cannes festival.

Rocking different outfits on one day, she managed to look chic and effortless at the same time. Her amazing gown at the premiere? Bet you were dying to rip it off her back too.
