Harem pants

Harem pants are trousers that are baggy in the legs but tight at the waist and ankles. They are supposed to have been worn by women in a harem in the Ottoman Empire. In the harem, they would probably have been see-through, although ones for modern everyday wear are opaque.

At various times (by feminists ca. 1850, by fashion designer Paul Poiret ca. 1910 etc.) there were attempts to introduce short skirts over harem pants as an alternative to the long cumbersome skirts of Victorian and Edwardian clothing, without notable success as far as mainstream fashion (though some women's bathing suits were constructed along similar lines).
