Fair Isle sweater L/XL

Pretty long sleeve grey mock turtleneck cardigan. Fair Isle motif is grey, white snowflakes with black accents. Nubby grey trim at neck, along buttons and at wrist, really good hand feel. Faux tortoise shell buttons. Cardigan is hip length. Unbranded, but does have a tag indicating size. It's marked XXL, but I think it's more of an XL. Fabric is acrylic yarn.
