This is a vintage Michiyuki
Coat with 'kikko'(tortoise shell) 'Hana-bishi' (flower diamond) pattern, which is dyed.
The vibrant pattern emerges out against the black background.
Textile is glossy damask effect(rinzu) silk with woven wave and 'kiri'(paulownia) pattern, and has soft touch.
The lining has dyed flying crane and 'ume'(Japanese plum) pattern.
It has whitish smudges in places, and they are slight but disturbing.(D)
There are other flaws such as loose stitches and small holes.
Please check detail photos.
Though it has some flaws by ages, please enjoy its full taste of vintage!
