Here is a gorgeous vintage long sleeve dress. Feels like mostly or all polyester. Super interesting geometric design under maroon. 21" zipper down the back. It's in incredible condition with years of life left! Here are the measurements taken laying flat. (please refer to the last photo above to see how I measure dresses)
