Authentic. Black. The quality label shows through, so it has been cut. The material is unknown. I think it's wool and nylon. It doesn't feel scratchy. I've worn it a few times. There are no stains, spots, or holes. Length 52cm, bust 84cm, shoulder width 38cm, sleeve length 55cm. The length isn't very long, so it's easy to pair with pants, denim, or skirts. This is a used item, so please refrain from purchasing if you are sensitive to such things.
