Historically the corset has always been a woman's underwear support, which was boned and close fitting and usually hooked and laced. The corset starts either above or just below the bust and continues down to the waist or below the hips, generally with garters attached to its base, thus assuring corset comfortable wearing. The corset has effectively evolved into a body-shaper, derived from sportswear, and featuring under-wiring of the breasts and elasticised control panels with popper fastenings at the crotch. Corset underware have long ago entered the lady's wardrobe, but instead of being long gone and forgotten, corsets are only increasing in their popularity over time. A Basque is the name given to any tight-fitting bodice garment worn by women. Examples of Basques include the corselette. The bustier on the other hand is a bosom-to-hip corset-like garment, usually trimmed in lace, that are needed for corset comfortable wearing. Other corset underware can include detachable garters, flexible boning, shoulder straps, and lace-up closing. Often these garments are worn for corset comfort, the visual enjoyment of a partner and are made from myriad of fabrics and materials including, lace, fine cotton, eyelet lace (broderie anglaise), matte and shiny silk and silk imitations, crepe de chine, georgette, and satin as well as more modern materials such as lycra, leather and rubber. Corset underware is typically constructed of a flexible material (like cloth or leather) stiffened with boning (also called ribs or stays) inserted into channels in the cloth or leather, to ensure corset comfort. In the Victorian period, steel and whalebone were favored. Plastic is now the most commonly used material in corset comfortable wearing; spring or spiral steel is preferred for high-quality corsets. Other materials used for boning include ivory, wood, and cane. (By contrast, a girdle is usually made of elasticized fabric, without boning.) The corset underwear fell from fashion in the 1920s in Europe and America, replaced by girdles and elastic brassieres, but survived as an article of costume. Originally an item of lingerie, the corset has become a popular item of outerwear in the fetish, BDSM and goth subcultures. In the fetish and BDSM literature, there is often much emphasis on tightlacing. In this case, the corset may still be underwear rather than outerwear. Another angle in corset comfort is the wearing of a corset while having an enema; the theory is that the corset comfortable wearing prevents the belly distending, enhancing the effects of the enema. (Putting on the corset after giving the enema will almost certainly cause the enema to be expelled.) Nowadays it is primarily ladies who make extensive use of corset wearing. Among the considerations which prompt corset wear over it for the sake of ultimate comfort. Since the late 1980s, the corset has experienced periodic revivals, which have usually originated in haute couture and which have occasionally trickled through to mainstream fashion. These revivals focus on the corset as an item of outerwear rather than underwear. The strongest of these corset comfort revivals was seen in the Autumn 2001 fashion collections and coincided with the release of the film Moulin Rouge!, the costumes for which featured many corset underware.
