I purchased this new with the intention of using it myself, but I only tried it on once (unsealed, tag removed), so it's in "almost new" condition. It's a SS size, but I believe adults around 160cm tall can wear it without any problems. In addition to being suitable for children's club activities or gym class, the bright colors are also fashionable, so I suggest that adults can also use it for everyday life, not just sports. Due to the size and design, it seems to be unisex and can be worn by people of all ages and genders. If you feel there's a need for it, please feel free to purchase it. - Model Number: XW1320
