This is a casual Tsumugi
opened Nagoya obi
with rainbow color abstract pattern, which is roughly woven.
Textile is rustic soft Tsumugi
silk with knobs of yarns.
Although it's not mentioned on the sheet and photo,
there is discoloration along the folding lines on upper 'otaiko'(square bow) and around 'maegara' (front patterned part).
The one on upper 'otaiko'(square bow) could be hidden when you tie it.
The other one around 'maegara' (front patterned part) will be seen when you tie it.
There are some other flaws such as folding lines.
For the details, please refer to the photos and sheet.
Enjoy wearing it as everyday clothes.
