This is a Tsumugi
kimono with simple stripe shibori (tie-dye) pattern, which is woven on chic stripe background.
Its design like the grain of wood is stylish.
Textile seems to be Oshima Tsumugi
silk and has soft and smooth touch, which is the feature of Oshima Tsumugi
Although it's not mentioned on the sheet and photos, there is a snag like flaw on top right shoulder.
There is not other prominent flaw.
Basting stitches remain and it may be just after cleaning.
Please enjoy this stylish design!
