The manufacturer and size are unknown, but I wore this when I was wearing size 80 clothing, and I think it was probably Korean clothing. It's made of velour fabric, so you can wear it for a long time in winter, spring, and autumn. I wore it with tights in the winter. It's loose-fitting and has a gathered, stylish, and cute look. There are no noticeable stains, so I think you can still use it, but please consider that it is a used item before purchasing.
