GU 150 size blue denim jacket, 100% cotton material for comfortable wear. New, unused, but there is discoloration from the center of the back to the left side. It's easier to see on the lining side. It might be considered part of the denim's texture, but please refrain from purchasing if you are concerned. - Brand: GU - Color: Blue - Size: 150 - Style: Denim Jacket - Material: 100% Cotton Thank you for viewing.
