Thanks to a little thing called Twilight, Kristen Stewart has become a household name, not to mention a style icon. We love seeing her stroll the city in jeans and Converse, then getting dolled up for a swanky party or premiere in designers like Marchesa, Elie Saab, and Balenciaga. Since today marks Miss Stewart's 23rd birthday, we're celebrating in a major way. We've already taken a look back at her red-carpet style - now we're wishing Kristen a very glossy birthday by peeping her most fashionable editorials. Click through to see each one, and make sure to let us know your faves in the comments!
