I purchased this as a size M, but it doesn't have tags from the beginning. The material is unknown. There's a scratch on the inside of the collar. Width is about 60cm, length is about 82cm (sorry for the error). I think it's about XL. It's been washed and only tried on. It's quite large, so I'm selling it. Please refrain from purchasing if you are concerned. I apologize if I missed anything. Price reduced. No returns or refunds, please. I will fold it up small for shipping.
