Polonaise (clothing)
The robe à la polonaise or polonaise is a woman's garment of the later 1770s and 1780s or a similar revival style of the 1870s inspired by Polish national costume, consisting of a gown with a cutaway, draped and swagged overskirt, worn over an underskirt or petticoat. From the late nineteenth century, the term polonaise also described a fitted overdress which extended into long panels over the underskirt, but was not necessarily draped or swagged.
