This is a simple Tsumugi
Kimono with a horizontal stripe pattern, which is woven with Kikko-Kasuri technique.
Textile is exquisite silk and has soft, but nubby touch.
The collar is hiro-eri(unfolded).
Basting stitches remain on sleeves and it seems to be just after cleaning.
It has very prominent patinas on left chest (B), but the other patinas are rather slight.
There is a rather noticeable stain on left front collar (C).
It has wear and right front collar is rather prominent, although this part doesn't have flaw photo. (*It can be hidden when worn.)
Discoloration on the overall background and discoloration on the lining are slight.
There are a couple of other flaws.
Please check detail photos.
