What better way to show off Boy. by Band of Outsiders ' prairie-inspired Fall collection than with Amy Adams  playing an irreverent cowgirl? Following in the footsteps of the label's other campaign darlings, like Michelle Williams  and Kirsten Dunst , Adams channels Outsiders' quirky-cool for the Fall Polaroid  shots, shooting off toy guns, playing gymnast, and drinking from a flask, all, of course, while showing off the pretty, Western-inspired prairie dresses and menswear-style suiting. It's not the Amy Adams we remember from Enchanted, but we kind of love the way she can improvise with a jungle gym and a herd of buffalo.
