I bought this but haven't worn it much, so I'm selling it. I wore it at its smallest size, and my child also wore it. Adults can wear it too. The adjustable part is well-made! If you look closely, there's a little bit of pilling in the first image, but I don't think it shows any signs of wear. I don't see any stains, but since it's been stored at home, please refrain from purchasing if you are sensitive to these things or if you are looking for a perfect item. It will be shipped folded compactly. Please understand this before purchasing. KAIJU Sea Monster Aquarium Sea Animals Whale Polar Bear Dolphin Size...Free Color...Blue系 (Blue-based)
