Junko Katoh For NOBLE Pants from the Junko Katoh collaboration series. These are made of a white satin-like or silk-like material and were very popular. The tag says 100% acetate. I really wanted these and was given them, but I've gained weight and can no longer wear them, so I'm selling them. I've only worn them once since I received them. Acetate wrinkles easily, so there are wrinkles overall. I haven't found any particularly large stains as far as I can see, but there is a general feeling of use. I think these are hard to find even used. Perfect for the coming season.
