This is an appealing shibori yukata
with charming flower pattern.
It is dyed in Narumi
or Arimatsu, famous shibori
It has no lining attached.
Textile is cotton and has soft and slightly bumpy touch.
The stain B seems more like patinas, and in places of the white areas(flowers) have same type of patinas. (however, they are not too prominent)
There are other flaws as the photos show, but overall, it is in very good condition.
