This is an Oshima Tsumugi
Kimono with vivid "Karabana"(imaginary Chinese flower) pattern, which is woven with double ikat technique.
Textile is Tsumugi
silk with smooth and crisp texture, which is the feature of Oshima Tsumugi
Basting stitches remain, so it seems to be after cleaning.
It was made by Mitsukoshi, one of the high end department stores in Japan.
There are small patinas which are not that noticeable.
There is a faint stain(E) on the back bodice.
There are some other flaws such as discoloration and patinas on the lining, small snags on the outside.
For the details, please refer to the photos and figure.
Although it has such flaws, it is still in wearable condition.
Enjoy wearing it as everyday clothes.
