This is a genuine stone island jumper. It was actually a man’s size large jumper but I accidentally shrunk it. It’s now the size of a 10 year old child but because I’m not certain what size boy/girl this would fit I have shown the measurements. The size originally was. Large. This is in excellent condition as it had only been worn 3 times before I shrunk it so was totally gutted. It is Navy and is 100% wool and the stone island badge on sleeve comes off as it is held by buttons.
