This is a Duras Ambient knit. The size is F. I bought it several years ago and it's new and unused. The knit has large stitches, so I think an inner layer is necessary. I took a picture with the tag (photo 5). Here are the approximate measurements (measured by hand): Length (from shoulder to hem): about 57 cm Width (armpit to armpit): about 47 cm I believe there are no noticeable stains, but please understand that I may have missed something, and as it's a knit, there may be seams at the ends of the knitting, so please refrain from purchasing if you are looking for a perfect item. Please understand that it has been stored at home. It will be folded and shipped. Feel free to ask any questions in the comments.
