It's likely because you received the correct size (according to their logic).
A Japanese women's medium (the only other size available in extremely low-end costumes) is a US women's small. The XL or Men's option is the closest available to a US women's large.
A Japanese mens' medium is only slightly larger than a US women's large. They were probably just selling the mens' size as their unisex large overseas.
