The female breasts have very little internal support, being composed largely of adipose tissue. It is believed that the primary anatomical support for the breast is provided by the Cooper's ligaments, with the skin covering the breasts offering some additional support. However, this anatomical support is usually insufficient to hold the breasts up (especially in older women), and to prevent movement of the breasts, which can cause pain and discomfort. The primary reason for wearing a brassiere or similar foundation garment is thus to provide external support for the breasts, both to increase comfort and to provide a sexually alluring figure. Push-up bras, are a type of bra that has additional padding, and is structured so that the breasts are lifted and the cleavage emphasised.
The best known brand of push- up bras is the Wonderbra. Minimizer bras have the opposite effect to push up bras, and are worn by large busted women who wish to make their busts appear smaller.
In 1992, Wonderbra - a padded, underwired push-up bra- was launched and took the world by storm. By the late 1990s, the bra or brassiere had became one of the most complex pieces of lingerie, made with up to 43 different components.
Bra, an informal shortening of the term brassiere, was first introduced in the 1920s. Just as its name changed through the decades, so did its rationale. With bras women's breasts are lifted, enlarged, supported, revealed, and covered throughout the decades. By the 1930's, it was recognised that the measurement of the bust and the size of the breasts needed two different scales (A, B. C, D). The first strapless bra appeared in 1934, and a little later, underwired bras were worn to give breasts a more substantial silhouette. In the forties bras with additional padding were introduced.
Push-up bras followed and a myriad of styles developed including, the balconette bra
that's when breasts are lifted; the classic sheer bra to provide a smooth outline; t-shirt bra with woven cups; as well as sports bras, seamless bras, strapless and shelf bras. Push-up bras have additional padding at the bottom portion of the cup, which lifts the bosom and gives the illusion of a fuller bust. Because of their complexity push-up bras come in a combination of and wide range of fabrics. While fine cottons were always a staple, silk net satin, brocade, nylon, jersey and lace bras were and are popular together with satin imitations like Lycra silk, satin crepe de chine, tactel and polyester.
Many women claim that push-up bras, if selected correctly, can literally do wonders in terms of adding shape to the breasts. Special innovative push-up bras were created, that have silicone or water inserts which efficiently imitate the natural fullness of women's breasts.
Push-up bras are indispensable not only for the sake of enhancing the look of the breasts, they serve as necessary support. Push-up bras are available in all sizes, besides there is a staggering diversity in cup shapes and strap types.
There are also push-up bras with removable pillows of inserts in the cups as well as detachable straps.
