Hakama

Hakama (袴^?) are a type of traditional Japanese clothing. They were originally worn only by men, but today they are worn by both sexes.

While hakama used to be a required part of men's wear, nowadays typical Japanese men usually wear hakama only on extremely formal occasions and at tea ceremonies, weddings, and funerals. Hakama are also regularly worn by practitioners of a variety of martial arts, such as kendo, iaido, taido, aikido, ryu-te, and kyūdō.

Women's hakama differ from men's in a variety of ways, most notably fabric design and method of tying.

... women rarely wear hakama except at graduation ceremonies and for traditional Japanese sports such as kyudo, some branches of aikido and kendo.^[1] Only very rarely are hakama worn by women at tea ceremony.
