This is a fashionable Tsumugi Nagoya obi
with a design of 'Hana-bishi' (flower diamond), which is dyed with Shibori (tie-dye) technique.
Its 'somewake'(dyed with separate colors) background is impressive!
Textile is Tsumugi
silk and has soft and nubby touch.
There are molds on otaiko and they will appear when tied.
However, they are slight so not prominent.
Please check detail photos.
If these flaws do not bother you, it could be still worn.
Please enjoy its charming fashion as a daily wear!
