This is an American-designed T-shirt that is not sold in Japan. The size is XS, but since it's American sizing, it's probably a Japanese S to M. Measured by an amateur, the length is about 55cm and the bust width is about 34cm. You'll stand out at events and Halloween! My child only wore it once for a short time as a Halloween costume. If you purchase it with other items I have for sale, I will offer a discount! USA American American Stars and Stripes Halloween #HalloweenOnMercari
