History of corsets
Corsets were first widely worn during the 16th century (first attested in Spain in the late 15th century as a upper part of the spread skirts of the incipient farthingale), and generally remained a feature of fashionable dress until the French Revolution (1789). These corsets were mainly designed to turn the torso into the fashionable cylindrical shape, although they narrowed the waist as well. They had shoulder straps; they ended at the waist; they flattened the bust, and in so doing, pushed the breasts up. The emphasis of the corset was less on the smallness of the waist than on the contrast between the rigid flatness of the bodice front and the curving tops of the breasts peeking over the top of the corset.
The corset then went into eclipse. Fashion embraced the Empire silhouette: a Graeco-Roman style, with the scanty skirts gathered under the bosom and the waist de-emphasised, and dresses sewn from thin muslins rather than the heavy brocades and satins of aristocratic high fashion.
The reign of the Empire waist was short. In the 1830s, shoulders widened (with puffy gigot sleeves or flounces), skirts widened (layers of stiffened petticoats), and the waist narrowed and migrated towards its "natural" position. By the 1850s, exaggerated shoulders were out of fashion and waistlines were cinched at the natural waist, above a wide skirt. Fashion had achieved what we now tend to remember as the Victorian silhouette.
Before the mid-19th century, the prevailing term in English was "pair of stays; ladies stays; girls stays" (but "corset in French).
In the 1830s, the artificially inflated shoulders and skirts made the intervening waist look narrow, even with the corset laced only moderately. When the exaggerated shoulders disappeared, the waist itself had to be cinched tightly in order to achieve the same effect. It is in the 1840s and 1850s that tightlacing is first recorded. It was ordinary fashion taken to an extreme. The Victorian and Edwardian corset differed from earlier corsets in numerous ways. The corset no longer ended at the waist, but flared out and ended several inches below the waist. The corset was exaggeratedly curvaceous rather than cylindrical.
15th century 
NOTE: This image does not actually depict a "corset" in the usual modern sense of the word (a woman's undergarment intended to constrict and/or support the torso), but "corset" in the original medieval French and German sense of the word.
It is common as women's clothes take the name from men's clothes.

At the Great Exhibition in 1851 Madame Roxey Ann Caplin was awarded the prize medal of "Manufacturer, Designer and Inventor" for her corsetry designs, as the only corsetmaker who get a prize by the Great Exhibition. This prize medal change the corsetry of England.
The shoulder straps disappear from some adult ladies's corsets.

This era have three types of corsets
Thin waistline, full hip, medium curved back
1908-c. 1914 Post-Edwardian long line 
The tight waist end in 1908. 'From 1908 to 1913 the style of dresses became slimmer through the lower waist and hips, so corsets grew longer. A new type of fashionable corset covered the thighs and changed the position of the hip, making the waist become both higher and wider. The new fashion was considered uncomfortable, cumbersome, and furthermore required the use of strips of elastic fabric.
The corset is long and have a small high curved back.
1913-1914 The longest long line corset 
Corset by legs. Many older corset was continuous in use, but the new corset in this year was extreme long.
Corset, shorter shorter and loose. A suggestion of belly. The long corset be at the hip, not at the waist as before. Because the hip move in position to the chest, this corset have need of a brassiere.
Corselettes 1918-1960 
The corselette was often something like a single garment combining the functions of brassiere and girdle (in the 1920's, it was often worn with the object of achieving a boyish figure). The corset in that era was as long girdle by spiral springs.
1960- 1980 
Panty hose has largely displaced girdles and corselettes from common use.
The corset get a rebirth as visible dress.
