Flat measurement: Length from shoulder approximately 73cm (front), 75cm (back). Slits at the side seams. Width approximately 70cm. There may be some error. The material is unknown. The turtleneck is not included. This is a tunic made by deconstructing, washing, and remaking an old kimono. The color is a bit more green. Because of the width, it's suitable for those size L or larger. I, who am size M, can wear it, but it felt loose. This is handmade. There may be imperfections, so please purchase only if you understand and accept this.
