This is a fully authentic item with the tag. It was originally long-sleeved, but it didn't look quite right on me, so I cut the sleeves and sewed them to make it short-sleeved. Therefore, there are some loose threads as shown in the 4th and 5th photos, but there are no particular problems such as fraying when wearing it. I am selling it at a lower price because it has been re-sewn and there is some yellowing around the neck as shown in the 3rd photo.
