Purchased from Pet Paradise. The size is SS for girls. It's for dogs up to 5kg, but mine is a bit big at 3.6kg, so I'm offering this to someone who needs it. My dog is 3.6kg, so 3S size is too small (up to 3kg), and 2S is too big (up to 5kg), so it might be a little large depending on the item. It's thin, so it's recommended for spring, as an inner layer under a coat, or for wearing at home. It's new, but please understand that there may be initial scratches or stains. Pink dog clothes with ribbon decoration, made of soft fabric for comfort. - Color: Pink - Size: SS - Manufacturer: CREATIVE YOKO CO., LTD. - Design: Ribbon decoration - Material: Soft fabric - Price: 3,630 yen
