NWT Dress the Population Tiffany One-Shoulder Sheath Dress in Black Reposhing this item I purchased from @fleetwood77. Loved it, purchased for a wedding but did not wear it. Still NWT! The Tiffany is an elegant asymmetrical dress made in a stretch crepe material in Black. A large bow drapes over the single shoulder strap. The form-fitting silhouette has a straight, midi-length skirt that tapers in at the waist completed with a back slit. Questions? Leave a comment below!
