Here is a stunning short sleeve dress by Marian Sue. Feels like mostly or all polyester. Jet black fabric with bold and vibrant floral pattern throughout. High waist with built in tie. Sixteen inch zipper down the back. It has a very subtle almost velvet feel. Fairly sheer, soft, and comfy. It's in amazing shape and has years of life left. Here are the exact measurements (be sure to reference the last photo to see how I measure dresses)
