This is an elegant Houmongi
kimono with a design of houou(phoenix), butterfly and treasure on stream and 'doukyo'(copper mirror), which is dyed.
Textile is silk and it has soft touch.
It has basting stitches and seems just been cleaned.
It seems to be made by Mitsukoshi, one of the high end department stores in Japan.
It has a embroidered kamon(family crest).
It has discoloration overall, especially, back left bodice one is rather prominent and disturbing.
Please check detail photos.
If these flaws do not bother you, it could be still worn.
Please enjoy its graceful fashion!
