I wore it once. There is no size notation. I think it's probably 21-23 cm. My daughter, who is tall and slightly slender, used it when she was in the 4th grade. These are zori sandals with a wooden sole and purple and yellow floral straps. A 140cm yukata is also listed on a separate page. - Color: Purple and yellow floral pattern - Material: Wooden sole and cloth straps - Size: Approximately 22cm
