I bought this for a mixed-breed dog I had at my parents' house, but he hated wearing it and I never used it. It's suitable for rainy days or winter walks. The 4XL size is: bust 65cm, back length 52cm, neck circumference 52cm. My dog passed away this year due to old age. So, I no longer have a dog to wear it, and I'm offering it for sale in the hope that someone else can use it. (^ー^)
