Men's Oshima Tsumugi? Black with blue ensemble

This is a tsumugi ensemble (long kimono and haori) that was at my parents' house.
I was told it was Oshima Tsumugi, but I don't know the details.
It feels light and somewhat soft.
The base color is black with light blue accents. When viewed up close, the pattern in the 8th image seems to be the most accurate representation of the actual color, but when viewed from a distance, it appears overall light blue.
The haori still has its stitching and appears unused, but there is a stain on the right shoulder to chest area. It blends in with the pattern and is not very noticeable.
The long kimono has a small hole on the inside of the right sleeve. There are signs of repair. There also appear to be loose threads, small holes, and stains.
They are not very noticeable due to the color and pattern, but please be aware.
