This red Preen By Thornton Bregazzi Cyra silk dress features an asymmetric off-the-shoulder design with short sleeves, a fitted waist, shoulder straps, a concealed zip fastener at the back, and a pleated mid-length skirt. To paraphrase the great David Bowie, we'll be putting on our red dress and dancing the blues in this gorgeous Preen By Thornton Bregazzi gown to the ball tonight (at a Duke's home, of all places).
