Size 38, which according to research is equivalent to a Japanese size 13. I've listed it as a Large. I measured the garment just to be sure. Measurements taken flat: Length 55cm, Width 43cm, Shoulder width 34cm. There may be some slight variations. For reference. Back zip, high-collared lace, lace hem. It has a luxurious feel. I bought it, but I haven't had a chance to wear it, so would anyone who likes it be interested? Please note that returns are not accepted. Please purchase after referring to my profile. If you have any questions, please ask. Thank you.
