The August issue of InStyle features a stunning 8-page fashion story starring True Blood actress Deborah Ann Woll. And while the statuesque, alabaster-skinned redhead makes the perfect model for designer Marc Jacobs' acclaimed Fall 2010 collection—she poses in four very different, very dramatic dresses and a fur-trimmed tweed coat—the 25-year-old confessed on set that it was, in fact, her first-ever fashion shoot. "I'm very new to all this," she admitted. "Growing up, I made some of my own clothes. I still have jeans that I was wearing five or six years ago. I'm not a fashion maven." Maybe not, but she is gorgeous. See the rest of the pictures—and read fashion director Hal Rubenstein's interview with Marc Jacobs—in the current InStyle, available on newstands now!
