This is an amazing dress - it is black crepe fabric, probably some kind of synthetic, but a heavy weave, so that it drapes beautifully. It is cut on the bias, and has amazing give and stretch (that's why I'm pulling it out in one picture - to show the fabric give). I have lent this dress to friends from size 4 to size 10, from barely 5 ft. tall to almost 6 ft. tall and every single person looked beautiful in it. It's time to share it with others. The plain details on it: Size: I can't find a size tag any more, but as mentioned, it's quite adaptable. Probably started as a size 6 or 8. Material: best guess is a weighty rayon or polyester - drapes beautifully, never wrinkles, but dry clean only Length: anywhere from mid-calf to ankle length Condition: remarkable, no stains, pulls, frays, etc.
