NWT, only tried on and just a little too snug when I tried to zip it. I would say this fits a 0. Commense makes you pay to send back the dress, so going to take a hit and sell it. Gorgeous black and white halter maxi dress with a flattering V-neck and defined waist. Lightweight and breathable fabric for comfortable all-day wear. Vertical stripes create a lengthening silhouette. Perfect for casual outings or dressed-up evenings.
