Paola Cossentino x Gaâla Limited Edition Collection This stunning, elegant midi-length backless dress features long trumpet sleeves, a low-back tie silk tie, and silk-covered button enclosure at the back of the neck. Bodice is fitted throughout with a slight mermaid cut to give this dress gorgeous movement while showing off your curves. Perfect for attending the Opera, a black-tie wedding, or for a romantic date night (Valentines Day, anyone?). Material is 97% Silk, 3% Elastane; and Gaâla Paris sizes this dress as a French 38, I would say it is between an American size 6 and 8. Measures 14 inches across waist; there is a bit of give because of the 3% elastane material and the backless cut. Free shipping offered.
