The robe de style describes a style of dress popular in the 1920s as an alternative to the straight-cut chemise dress.
The bodice could be fitted, or straight-cut in the chemise manner, with a dropped waist, but it was the full skirt that denoted the robe de style.
Sometimes the fullness was supported with petticoats, panniers, or hoops.
The robe de style was a signature design of the couturier Jeanne Lanvin.
