They are usually sold in size M, so I buy size M. In fact, the smaller size is size S and the smaller size is size xxxs, but generally this size is not sold, it is too small and too few people buy it. So it is difficult for small men to buy clothes. Since then, a treasure has no average size, only unsuitable.
