Thank you for viewing. As it's getting cold, I think this would be warm and useful for children when they wake up. It's been worn a few times, and there doesn't seem to be any noticeable stains. I'd like to give it away to someone before I get rid of it. Length: Approximately 51cm Width: Approximately 35cm I'm not sure about the size, so please measure it while your child is wearing it. It has a zipper. It will be compressed for packaging. Thank you for your understanding.
