A costume from "The Duchess" (2008) starring Keira Knightley as Georgiana, Duchess of Devonshire with costume design by Michael O'Connor. The duchess wore this purple silk court "robe a l'anglaise" to the theater. The fabric has a floral pattern edged at the bodice and sleeves with lace and small arrangements of silk flowers and velvet ribbons. The panniered underskirt is quilted. The overskirt is drawn up into the shape of petals, in a style called "polonaise."
