Shaped into a silhouette reminiscent of those favored by '50s screen sirens, the black Ellie dress from Preen by Thornton Bregazzi artfully showcases the décolleté with its off-the-shoulder neckline. Nipped in the waist and full in the skirt, this elegant style is crafted from lustrous stretch satin and features side pockets for glamorous nonchalance.
