This is a cotton cardigan. There appears to be a stain of about 2mm on the right shoulder, but it's hardly noticeable due to the ribbing. (It appeared more clearly in the photo.) It might come out with washing. There is also some fading around the neckline. Please refrain from purchasing if you are concerned. It's also recommended for formal occasions and other situations where you need to dress properly. Purchased from a Gallery Vie store.
