Stunning vintage dress by Walden classics. I'm assuming it's a size medium to large based on the measurements. The material is very lightweight and breathable. It's also quite sheer. It's a really beautiful dress that I've worn a couple of times myself. Gorgeous, rich floral pattern. Measurements are as follows: Bust: 19 inches flat Waist: 15 inches flat Length: 25 inches long ( measured from waist) Sleeve: 4 inches long.
