Thank you for viewing! I bought this a few years ago, but I've kept it hanging on a hanger without wearing it. Size 40 is probably a size L, but when I tried it on over a knit top for this listing, it felt like a tight fit, so I think it would fit someone who wears a size M. The innerwear the mannequin is wearing is not for sale. I don't remember wearing it, but it has been stored at home for a long time, so please refrain from purchasing if you are very particular or if you are nervous about used items. ◎ Please read the profile before commenting and purchasing.
