The size is listed as 40, which I believe corresponds to a size L. No lining. Elastic in the back from the waist down. Zipper in the back, from the upper back. Pullover style. I'm selling this as I'm going through my wardrobe. It's not new, so there might be some loose threads, but I don't think there are any noticeable stains or fabric tears. To save on shipping costs, I will compress the item. If you prefer it not to be compressed, please bear the extra cost. Please contact me if you have any questions.
