I bought this new and only tried it on. I bought it for my Italian Greyhound, but the length is a few centimeters too short, and it seems tight, so I'm selling it. The fabric is fleece-lined, thick, and seems warm. You can attach a leash directly, making walks very easy ❁⃘*.゜ Size...M I also have a turtleneck romper in a similar size. I can offer a discount on shipping if you purchase multiple items (*^^*)
