This is a vintage men's juban(undergarment) made of kimono pattern sample fabric. So it has various dyed pattern in one fabric.
We sometime come across women's pattern sample juban, but men's like this piece is very rare. In the left chest, nostalgic baseball pattern can be found.
Textile is plain silk, and has soft and smooth touch.
It has some flaws as photos show, but as a whole it is in very good condition.
*Softness ( Exceptionally Soft, □ Soft, Medium, Comparatively Stiff, Stiff )
