There is a slightly frayed area on the back (see photo 4), which is why this item is priced as it is. I couldn't find any other stains, and the material is comfortable to wear. It may have shrunk slightly as it was worn for one season. Rib-knit sweater with a turtleneck design, made of soft acrylic material for a comfortable feel. - Brand: Je chichi - Size: W - Material: 62% Acrylic, 25% Nylon, 13% Polyurethane - Design: Turtleneck, Ribbed knit Thank you for looking.
