This is a collaboration item between GU and beautiful people. The size is L. The color is black. It was very popular at the time, and I purchased it at the store on the day of its release. However, I haven't had a chance to wear it, and I realized it had been sitting in my closet, so I'm putting it up for sale. It's a new, unused item with tags. I will fold it up small and pack it for shipping. Feel free to comment.
