I purchased this online. The white lace peeks out and is very cute ´ᴗ` The size is S. ※ The tag had a number like 12 written on it from the time of purchase. See photo 3. I have a Chihuahua, and I put this on her once when she weighed less than 2kg. I have many other clothes, so I didn't use this much. I'm selling it because she got too big for it.
