Stunning black dress Sleeveless Mock lace neckline; Sweetheart neck lining Hidden back zipper; Hook-and-eye closure with keyhole design Online reviewers from the manufacture's web site were low because the zipper sticks due to the delicate fabric. I found this to be accurate but not insurmountable. The dress is truly stunning. I suggest that you NOT buy this dress if you are larger than a US size 6. The sizing is accurate and the garment will not hang right if you're not a true size 6.
