Now that Beyoncé has deemed her "so Brooklyn," Solange Knowles is a natural fit for Madewell's fall ad campaign. Here she is, posing in boyfriend jeans and polka dots, looking picturesque in orangey-pink lipstick and wearing a fedora atop her fluffy curls. This is Solange's first major contract with a clothing label; she previously modeled for Rimmel London in 2011; served as a "brand ambassador" for Armani in 2008; and appeared with AnnaLynne McCord, Sophia Bush, Joel Madden, Brody Jenner, Cody Linley, and Bow Wow in ads for a juniors line called Op in 2009. In other words, this is a big step up! Enjoy this exclusive behind-the-scenes video from the campaign shoot.
