Kimono Men's Adult Kimono and Haori Set

Material
Size
I apologize for my lack of knowledge.
I don't know how to measure it, how to fold it, or anything else.
This is a kimono that my father had custom-made when he was young.
He was about 180cm tall.
I also have no idea about the material!
I don't know its value either!

I believe it's been about 50 years since it was made,
but isn't it in good condition?

I'm not confident I can fold it properly anymore, so I might be in trouble if you have specific requests...
Everything is sold together. By the way, my father is doing well.
It has never been worn.
