PLEASE READ!! This is NOT the ModCloth fair isle ghost sweater. It is a dupe from Amazon. No tags of any kind, but I am certain the material is all synthetic. Was “one size” but I would not buy this for anything over a size 6, which is why I listed it as a small. It’s adorable and looks soooo close to the real ModCloth one. It is a knit and has some stretch, 17” pit to pit when unstretched. I personally only ever washed on cold, delicate, and hung dry. No flaws that I am aware of.
