I bought this on Mercari, but it was too big for me. I received it as a new item, and I tried it on. When I, who am 155cm tall with a bust of 80cm and a waist of 56cm, wear it, the width is too large, and the shoulders slip down. I really liked the appearance, with its refreshing, spring-like color, but I would like to sell it to someone who fits the size. The size is listed as XS, but it's probably around a size M.
