Kristen Stewart's Style Evolution (PHOTOS)

For some, actress Kristen Stewart may always be Bella Swan, the protagonist of "The Twilight Saga," who is lucky enough to kiss both Robert Pattinson and Taylor Lautner on camera. Those who are old enough to remember, however, might recall the once blond actress' role as Jodie Foster's daughter in "Panic Room."

Unlike other child stars, Stewart is making a graceful (and fashionable) transition to adulthood. Recently named the face of Balenciaga's new perfume, Stewart's red carpet style is often funky and offbeat. It's no surprise that the actress, who also played Joan Jett in The Runaways alongside Dakota Fanning in 2010, has become a style star along the way.
