Dog clothes. The vest has a chest measurement of approximately 38cm and a length of 21cm. It is not stretchy. I think I've put it on about 3 times. I didn't see any noticeable stains. The bear pouch had a safety pin on the back, but it came off, so you'll need to figure out how to attach it to the clothes yourself. Please be aware of this. Because it's a product from overseas, there may be some areas where the sewing isn't perfect.
