Kimono slip, Hadajuban, Shiromuku, Uchikake

This item is over 40 years old.
I believe it is a Japanese-style slip made for a bride's attire.
The neckline is designed to be deep, making it ideal for formal occasions or when wearing a deep neckline.
There is no material tag, but based on its appearance, I believe the fabric is: upper part (100% cotton), lower part (100% cupra).
I would appreciate it if you could judge from the photos.
There is a stain in photo 8.
This is a long-term storage item. I believe it is likely new.
I am listing it because I don't think it will be used in the future.
