Cool Cool Plus material by Cuckoo Couture. This cool T-shirt features a smiling icon and a mesh body with a star pattern. It didn't suit my dog, so (*´-`) Although the tag has been removed and it's been washed, it's practically only been tried on. Size: ST. See the size chart in the 6th image for details. My Yorkie, who weighs 2.5 to 3 kg, wore it. A different color of the same size is also on sale. Please refrain from price negotiations.
