Panther-sleek, indulgent “Sylvie” elongates and flatters in black silk crepe. This is the perfect piece to show off arms and shoulders, with a halter-style top that is embroidered and embellished with silken flutters that continue, decadently, down to the waist. The slimming cut flares fluidly over hips and down to the floor in an A-line shape that ends in a pretty train behind, with a back that scoops low for a beautifully bare view. This dress closes with a zipper at the center of the lower back.
