Beautiful, artsy, Joseph Ribcoff cardigan size 8 to 10

This is a beautiful fluid cardigan that is taupe and black with a slight sheen. Pit to pit measurement is 19 inches but I believe could be worn by a size 8 or 10 body. Length is 30.5 inches, with three-quarter length sleeves. Material tag not present, but appears to be a polyester rayon type mix. It needs no steaming.
