JEKYLL EGG tank top Size: XXL (Manufacturer's size. Not for large dogs.) Please refer to the photos on the brand's website for wearing examples and sizing. ※ This is not the exact same product. It's a cute design with brown and white stripes, made of 100% cotton. I bought it when my dog was about 10kg and wore it a couple of times, but he gained about 3kg and it no longer fits, so I'm selling it. It has been washed at home.
