Vintage Jessica McClintock burgundy midi dress. Cream colored lace neckline. Mutton sleeves that button up the forearm. Buttons down the back. Shoulder pads and puff sleeves. And I’m not sure but it seems to have pockets on the sides. I don’t know if it’s supposed to add material at the waist or if it’s fold in pockets. Small stain under the lace neckline, see picture. Made from acetate and rayon. Women’s size 8, but it looks like it runs smaller. Measurements lying flat Armpit to armpit is approximately 18 inches Shoulder to hem is approximately 43 inches long
