Twilights‘s Bella turned rockin’ Joan Jett, Kristen Stewart and the rest of The Runaways crew, including Joan Jett, pose for pictures again at the Sundance Film Festival. Today Kristen‘s denim of choice is J Brand Crinkle Legging Jeans in Viper Black. I love these. They look like really thin leather pants. Clearly Kristen‘s look of choice at the moment.
