This is a fabulous sleeveless dress that has a '90s feel to it. It zips up the back and has a matching satin belt that snaps closed. I really love this dress and the only reason I'm selling it is because it's a little big on me now. I would say it might run a little small for a size 42 though (which is a US 6), but see the measurements below from the actual dress. It is self-lined and has a back vent. Wear with heels of choice or even dressier flats. Overall, it is in excellent, pre-owned condition; it just has a few faint markings on the front and what appears to be a pen mark near the bottom in the back. I imagine with a good dry cleaning, this would all come out.59% acetate, 36% nylon, 5% spandex. Dry clean.Measurements are approximate.Bust - 34-36Waist - 27-28Hips - 36-38Length - 40Back vent - 7 1/2
