This is a pajama from the Showa era. It's new, unused, and has been stored after being taken out of its bag. It's a size M, but I think it's a snug fit. It's a slim pajama that could be worn by a woman if you don't mind. The fabric is soft. There's a slight smell of mothballs. Please wash it and check for color fading. I think a woman could wear it if you don't mind. For those who don't mind the small details.
