It doesn't appear to have any noticeable stains, but there is some staining from the left shoulder to the armpit. There may be some other minor stains as well. The ribbon in the back can be retied. Since it's a larger size, I think it's about a size 13. Width: Approximately 56cm Length: Approximately 64cm Please note that these are amateur measurements, so please use them as a reference. I would appreciate it if you could understand that this has been stored at home. There are no smokers in my family. I do not have any pets. I will use recycled materials for packaging. My style of clothing has changed, so I would be happy if you would wear it. (^^)
