Size 3X silky soft stretchy swan dress, very good condition

Where to start..... I was told this dress is a size 3x, but the tags have been removed so I am adding measurements here to be sure it is accurate. it is approx 33" from pit to pit, and approx 41" long from top of shoulder to hemline. This dress is soft, silky, stretchy and super comfortable. It appears to be a Gloria Vanderbuilt dress, but I cannot swear by that. (the swans look very much like it) It has short sleeves and a round neckline. The photos look a bit like it is dark navy blue, but it is actually black. This dress is wonderful for comfortable travel. It falls below the knee, but could land right at the knee if you are taller. Please feel free to request any other photos or measurements. The condition of this dress is very good! I will ship it the same or next business day.
