This is a Tsumugi
Kimono with lovely butterfly in sideways blocks pattern, which is woven.
Textile is soft silk, and it has nubby touch.
Collar is hiro-eri (unfolded).
It has basting stitches so it might have been cleaned but there are light color stains shown as A and B.
The lining has slight discoloration. D is a stain caused by the hook but it comes inside and has no problem wearing.
Please see photos for details.
If you do not mind the small flaws, it can continue to be worn. WE hope you enjoy wearing the genteel color cute tsumugi!
