This is a vintage Meisen Michiyuki
with Sashiko embroidery-like fine geometrical pattern, which is woven.
Textile is silk, and it has soft to the touch.
Lining is jinken 'rayon'.
Discoloration on panels of the sleeves and the bodice are noticeably different. (D)
Slight patinas and discoloration are seen on both chest area, the back, and the bottom hem areas. (B.C)
It has some other flaws, such as smudge on the cuffs, as shown on photos.
Please see photos for details.
There are also snags in places. (sorry no photos)
There is a lump of snag, 3cm(1.17in), at about 22cm(8.58in) from the hem of left back panel.
Due to its old age, it has some flaws, but it still is a very stylish michiyuki.
