This is a Shioze Nagoya obi
with 'kiri'(paulownia) and 'tanzaku'(strip of paper) pattern, which is dyed.
Seasonal flowers and classical design is also dyed on it.
Its "Katazome"(stencil-dyed)-style vibrant pattern is eye-catching!
Textile is shioze silk, and it has relatively crisp and comfortable touch which is the feature of shioze silk.
Although not shown on the photo and figure, there is a small brownish stain on otaiko, and it is bothering a little with the sedate colored background.
It also has tiny patinas on the sedate colored background, but they are not so prominent.
There are other flaws such as slight discoloration and folding lines.
Please check detail photos.
If these flaws do not bother you, it could be still worn.
Please enjoy its stylish fashion!
