This vintage gem pairs just as well with a formal dress as it does with jeans and a t-shirt. 3/4 sleeve, polyester lining, worn open - no closures. There is no size tag but I called it a medium based on measurements, and is what I wear. Dimensions Length: 26" Armpit-to-armpit: 21" Outside is pretty perfect. Lining has a little tear that can be seen and minor stains. Please see pictures.
