Blonde Girl Strips Her Black Corset

In the 1820s, fashion changed again, with the waistline lowered back to almost the natural position. Corsets began to be made with some padding and boning. Corsets began to be worn by all classes of society. Some women made their own, while others bought their corsets. Corsets were one of the first mass produced garments for women. Corsets began to be more heavily boned in the 1840s. By 1850, steel boning became popular.
With the advent of metal eyelets, tight lacing became possible. The position of the eyelets changed, they were now situated across from one another at the back. The front was now fastened with a metal busk in front. Corsets were mostly white. The corsets of the 1850s-1860s were shorter than the corsets of the 19th century through 1840s. This was because of a change in the silhouette of women's fashion. The 1850s and 60s emphasized the hoopskirt. After the 1860s, when the hoop fell out of style, the corset became longer to mold the abdomen, exposed by the new lines of the princess or cuirass style.
During the Edwardian period, the straight front corset (also known as the S-Curve corset) was introduced. This corset was straight in front, with a pronounced curve at the back that forced the upper body forward, and the derrière out. This style was worn from 1900-1908.
The corset reached its longest length in the early 20th century. The longline corset at first 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. This style was meant to complement the new silhouette. It was a boneless style, much closer to a modern girdle than the traditional corset. The longline style was abandoned during World War I.
