Please read the self-introduction. Purchased during the cold season this year and worn as indoor wear, but outgrew it unexpectedly. Stored after home cleaning. I don't think there are any noticeable stains. Due to the material, there is some slight shrinkage after washing, but it can still be worn. I was thinking of having my dog wear it now, but it seems a little tight... Please consider it for puppies who quickly outgrow their clothes or for indoor wear, while it's still clean. Shipped via Yu-Packet Post.
