The trend for broad skirts slowly disappeared during the 1870s, as women started to prefer an even slimmer silhouette. Bodices remained at the natural waistline, necklines varied, while sleeves began under the shoulder line. An overskirt was commonly worn over the bodice, and secured into a large bow behind. Over time though, the overskirt shortened into a detached basque, resulting in an elongation of the bodice over the hips. As the bodices grew longer in 1873, the polonaise was thus introduced into the Victorian dress styles. A polonaise is a garment featuring both an overskirt and bodice together. The tournure was also introduced, and along with the polonaise, it created an illusion of an exaggerated rear end.
