This is a cosplay outfit of Mitsuri Kanroji from Demon Slayer: Kimetsu no Yaiba. It's a set including the demon slayer uniform (top and bottom, hole-punched type), socks, a shirt, and a haori. The size is likely S to M. I am 160cm tall and weigh 48-50kg, and it fit perfectly. (*^^*) If you purchase it by Thursday, I can lower the price by about 100 yen.
