This is a piece of clothing my sister's dog wore when it was a puppy. I think it's close to a size S. I'm a novice and this is my first time measuring, so there might be some errors. Neck: 27cm, Chest: 38.5cm, Back Length: 26.5cm, Front Length: 18cm Estimated weight: Up to about 3kg. It's a thin fabric with a little bit of stretch. I hope a small dog or puppy will wear it. Please refrain from purchasing if you are sensitive to items that have been handled by people, as this is used clothing. There is a small tear in the chest area. Please understand this before purchasing. Thank you for viewing. Pet supplies, dog clothes, dog goods, small dogs, puppies, used dog clothes
