Mourning Dress and Obi Set, Japanese Formal Wear, Kimono, Mon-tsuki (crested), Black, Checkered Pattern

Thank you for viewing.

I am not knowledgeable about kimonos, so please forgive me if there are any mistakes.

This is a set of mourning kimono and obi (sash).

○ Kimono
There are no stains on the collar, etc., so I think it has been used infrequently.
It has a lining, like a tomesode (formal kimono for married women), that is layered from the collar to the hem, which I believe is called hibaku.
There are some stains on the lining of the cuffs and hem where it is layered.
In my amateur opinion, it should be in a clean condition if the layered lining is removed.

It has a checkered pattern.
It has a little bit of wear and tear.

This item has been stored at my parents' house for a long time, so I would appreciate it if you could accept that it is a used item.
