The corset reached its longest length in the early 20th century. At first, the longline corset reached from the bust down to the upper thigh. There was also a style of longline corset that started under the bust, and necessitated the wearing of a brassiere, a style that was meant to complement the new silhouette. It was a boneless style, much closer to a modern [[Girdle (undergarment)|girdle]] than the traditional corset. From 1908 to 1914, the fashionable narrow-hipped and narrow-skirted silhouette necessitated the lengthening of the corset at its lower edge. Meanwhile, as [[bra]]s began to catch on in the 1910s, fewer and fewer corsets included bust support. The fashionable corsets of this period covered the thighs and changed the position of the hips, making the waist appear higher and wider and the hips narrower, forecasting the "flapper" silhouette of the 1920s.<ref name="Libes-2023" />  The new fashion was considered uncomfortable, cumbersome, and required the use of strips of elastic fabric. The development of rubberized [[Elastomer|elastic]] materials in 1911 helped the girdle replace the corset.<ref>Carlisle, Rodney (2004). ''Scientific American Inventions and Discoveries'', p.102.

In 1910, the physician [[Robert Latou Dickinson]] published "Toleration of the corset: Prescribing where one cannot proscribe", in which he investigated the medical effects of corsets, including the displacement and deformation of internal organs. He found that, while some women could wear these garments without apparent harm, the vast majority of users sustained permanent deformations and damage to their health. The purportedly healthier S-line corsets still restricted [[Diaphragmatic breathing|costal breathing]] and exerted pressure downwards on the pelvis.<ref name=Toleration>{{Cite wikisource | title=Toleration of the corset | last =Dickinson | first=Robert L. | year=1910}}</ref>

The longline style was abandoned during World War I, in part to save materials for the war effort. In the late 1940s and early 1950s, there was a brief revival of the corset in the form of the [[waist cincher]] sometimes called a "waspie". This was used to give the hourglass figure as dictated by [[Christian Dior]]'s "[[Christian Dior SA#The New Look|New Look]]". However, use of the waist cincher was restricted to [[haute couture]], and most women continued to use girdles. Waspies were also met with push-back from women's organizations in the United States, as well as female members of the British Parliament, because corsetry had been forbidden under rationing during [[World War II]].<ref name="Stevenson-2011" /> The revival ended when the New Look gave way to a less dramatically shaped silhouette.
