In 1906, when the S-curve silhouette was still overwhelmingly popular, Poiret introduced high waist corsetless dresses. He shifted the fashion trend substantially from 19th-century dresses in artistic forms with excessive decoration toward innovative clothing that accentuated the natural beauty of the human body. Although corsets did not disappear immediately, they were completely eliminated after World War I, following the new trend led by Poiret.
