There are stains on the cuffs and the stomach area. There is fluorescent pink pen on the left cuff. Both sleeves, in the area that touches the desk, are slightly yellowed. The stains on the stomach area are, upon closer inspection, a faint yellowish stain and two small brown stains. Please check the photos. It can be worn without any problems, and it's made of stretchy cotton with buttons that can be opened and closed, making it easy to put on. The size is labeled as 100, but it fits a child around 90cm perfectly, so it's a bit small. I'm selling it at a low price. Please purchase if you understand that this is used clothing.
