Sandro Black Lace Dress 2/4 Sleeveless Fit & Flare Holiday Cocktail Party

This is a really lovely fit & flare style black knee length dress that has a lace bodice and zips up the back. The main body of the skirt is a thin woven material. I'm not seeing this exact dress anywhere, but there is a similar one with a keyhole opening in the back. It is in excellent, pre-owned condition. I'm not seeing a size, but am guessing based on the measurements that it's a 2/4 (see measurements below). Lace -100% nylon; yoke - 93% rayon, 7% nylon; bottom - 100% rayon. Dry clean. Measurements are approximate. Bust - 32-35 Waist - 27-28 Hips - free Length - 35
