The actress features in an ethereal campaign to promote the high-fashion qualities of cotton.

Against the backdrop of her own closet, Bosworth models fashion-forward creations made from cotton by the likes of Prada, Rodarte and Nina Ricci, while singing a song based on the ongoing "Fabric of my Life" theme used by the American Cotton Incorporated for its TV campaigns.

"People generally think of cotton as cozy and casual," says stylist Cher Coulter, who worked on the ad. "But high end designers really capitalize on its versatility to the extent many people may not immediately recognize it as cotton."
