Elegant pearl gray Calvin Klein cocktail dress siy L

This dress is perfect for a less than formal second wedding or a summer cocktail party. I found no indication of the fabric, but it has some stretch to it. The bodice of wide pin tucks is the only part of the garment that is lined. it measures 18" pit to pit lying flat. The zipper in back measures 18" and the back of the garment measures 33". I found the condition to be very good pre-owned. Thanks for looking! As always, I will be happy to consider reasonable offers.
