This item is over 40 years old. It's a Japanese underslip, likely made for a bride's attire. The neckline is deeply cut, making it ideal for formal wear or when wearing garments with a low neckline. There's no material tag, but based on appearance, I believe the fabric is: Upper part (100% cotton), Lower part (100% cupro). I would appreciate it if you could judge from the photos. Photo 8 shows a stain. This item has been stored for a long time. I believe it's probably new. I don't think I'll have a chance to use it in the future, so I'm offering it for sale. Please consider purchasing if you don't mind the condition.
