Men's Kimono Set with Obi Belt

Men's kimono and obi set.

This belonged to my grandfather, and is from around the early Showa era, as it was from when my father passed away in his childhood.
My father recently passed away as well, and he never wore it because it didn't fit him.
The length of the kimono is approximately 160cm, so it's for a man.
There are three moth-eaten spots on the shoulders of the outer garment, and the white parts of the undergarment are stained, likely due to aging. I think it might improve a bit if washed. I have never washed a kimono, so I will pass it on as is.
The sleeves of the undergarment are stylish, so I think my grandfather was quite the kimono enthusiast.

I can take photos of other parts if you wish.
