The size is approximate. Please understand that there is no country of origin tag on this product. This tie-dye shirt was purchased in Thailand. The finish is quite different from Japanese ready-made products, so please only purchase if you appreciate this unique style. Please be sure to check the photos. There may be imperfections in the sewing, small holes, or fraying around the neckline. Since it's a shirt from a hot country, it's comfortable for Japanese summers. Wash with rinse or delicate detergent, and hand wash quickly. It dries in no time. Since it's dyed, it's recommended to wash it separately. It will be delivered by postal mail. Thank you for viewing.
