Japanese clothing accessory, Exlan, top and bottom set, M size, for autumn/winter. Bottoms are unused and in original packaging.

This is a Japanese clothing accessory.

It was stored at my parents' home.
The top piece does not have a bag.
I don't know if it was ever used.
The bottom piece appears to be as it was when purchased.

I don't know much about kimonos,
so I would be happy if someone could use it.

Thank you very much.
