The shell-shaped pattern that many people love is made of pure white fabric.
This is a homongi dyed with Itome Yuzen.
She has 3 shell buckets on the front of her top, 1 on the back, and 1 on each side of her sleeve.
It is dyed.
She seems to be a big hit at tea parties.
A gold bag sash or a green sash would probably go well with her.
