Formal wear kimono, mourning attire, for winter and summer, obi sash, 3-piece obi set, purchased at a kimono shop

This is a mourning dress that my mother had custom-made over 20 years ago.
It is being sold as a set including winter and summer garments, and an obi sash.
It has only been worn a few times.
There do not appear to be any noticeable stains, such as large ones.
My mother loves kimonos and purchased this from a high-end kimono shop.

It features a butterfly crest.

My mother is 158cm tall and has a standard build.
We hope this might be suitable for remaking into something new.
It has been stored in a chest for many years, but there is no peculiar odor.

Please consider this purchase only after understanding the above points.

There are no pets or smokers in the household.
