The breast is one of two prominences located on the upper ventral region of the torso among humans and other primates. Both sexes develop breasts from the same embryological tissues. The relative size and development of the breasts is a major secondary sex distinction between males and females.
Lingerie is a category of primarily women's clothing including undergarments, sleepwear, and lightweight robes. The choice of the word is often motivated by an intention to imply that the garments are alluring, fashionable, or both. In a 2015 US survey, 75% of women reported having worn "sexy lingerie" in their lifetime.
A corset is a support undergarment worn to hold and train the torso into the desired shape and posture. They are traditionally constructed out of fabric with boning made of whalebone or steel, a stiff panel in the front called a busk which holds the torso rigidly upright, and some form of lacing which allows the garment to be tightened. Corsets were an essential undergarment in European women's fashion from the 17th century to the early 20th century. In the 17th and 18th centuries they were commonly known as "stays" and had a more conical shape. This later evolved into the curvaceous 19th century form which is commonly associated with the corset today. By the beginning of the 20th century, shifting gender roles and the onsets of World War I and II led the corset to be largely discarded by mainstream fashion.
Preadolescence is a stage of human development following middle childhood and preceding adolescence. It commonly ends with the beginning of puberty. Preadolescence is commonly defined as ages 9–12 ending with the major onset of puberty. It may also be defined as simply the 2-year period before the major onset of puberty. Preadolescence can bring its own challenges and anxieties.
A nursing bra is a specialized brassiere that provides additional support to women who are lactating and permits comfortable breastfeeding without the need to remove the bra. This is accomplished by specially designed bra cups that include flaps which can be opened with one hand to expose the nipple. The flap is usually held closed with a simple clasp or hook.
The Wonderbra is a type of push-up underwire brassiere that gained worldwide prominence in the 1990s. Although the Wonderbra name was first trademarked in the U.S. in 1955, the brand was developed in Canada. Moses (Moe) Nadler, founder and majority owner of the Canadian Lady Corset Company, licensed the trademark for the Canadian market in 1939. By the 1960s the Canadian Lady brand had become known in Canada as "Wonderbra, the company." In 1961 the company introduced the Model 1300 plunge push-up bra. This bra became one of the best-selling Canadian styles and is virtually identical to today's Wonderbra.
Cleavage is the narrow depression or hollow between the breasts of a woman. The superior portion of cleavage may be accentuated by clothing such as a low-cut neckline that exposes the division, and often the term is used to describe the low neckline itself, instead of the term décolletage. Joseph Breen, head of the U.S. film industry's Production Code Administration, coined the term in its current meaning when evaluating the 1943 film The Outlaw, starring Jane Russell. The term was explained in Time magazine on August 5, 1946. It is most commonly used in the parlance of Western female fashion to refer to necklines that reveal or emphasize décolletage.
Fashion in the years following World War II is characterized by the resurgence of haute couture after the austerity of the war years. Square shoulders and short skirts were replaced by the soft femininity of Christian Dior's "New Look" silhouette, with its sweeping longer skirts, fitted waist, and rounded shoulders, which in turn gave way to an unfitted, structural look in the later 1950s.
Breast binding, also known as chest binding, is the flattening and hiding of breasts with constrictive materials such as cloth strips or purpose-built undergarments. Binders may also be used as alternatives to bras or for reasons of propriety.
Ptosis or sagging of the female breast is a natural consequence of aging. The rate at which a woman's breasts drop and the degree of ptosis depends on many factors. The key factors influencing breast ptosis over a woman's lifetime are cigarette smoking, her number of pregnancies, higher body mass index, larger bra cup size, and significant weight change. Post-menopausal women or people with collagen deficiencies may experience increased ptosis due to a loss of skin elasticity. Many women and medical professionals mistakenly believe that breastfeeding increases sagging. It is also commonly believed that the breast itself offers insufficient support and that wearing a bra prevents sagging, which has not been found to be true.
The history of bras is closely tied to the social status of women, the evolution of fashion, and shifting views of the female body over time.
Male bra – also known as a compression bra, compression vest, or gynecomastia vest – refers to brassieres that are worn by men. Men sometimes develop breasts and the estimates of those with the condition are presented as a range "because the definition of gynecomastia varies and the method of surveying varies." Although there are options for treating gynecomastia, some elect surgery to reduce their breasts or wear a male bra. Male bras typically flatten rather than lift.
Bra size indicates the size characteristics of a bra. While there is a number of bra sizing systems in use around the world, the bra sizes usually consist of a number, indicating the size of the band around the woman's torso, and one or more letters that indicate the breast cup size. Bra cup sizes were invented in 1932 while band sizes became popular in the 1940s. For convenience, because of the impracticality of determining the size dimensions of each breast, the volume of the bra cup, or cup size, is based on the difference between band length and over-the-bust measurement.
A bandeau is a garment comprising, in appearance, a strip of cloth. Today, the term frequently refers to a garment that wraps around a woman's breasts. It is usually part of a bikini in sports or swimwear. It is similar to a tube top, but narrower. It is usually strapless, sleeveless, and off the shoulder. Bandeaux are commonly made from elastic material to stop them from slipping down, or are tied or pinned at the back or front. In the first half of the 20th century, a "bandeau" was a narrow band worn by women to bind the hair, or as part of a headdress.
A bra, short for brassiere or brassière, is a form-fitting underwear that is primarily used to support and cover a woman's breasts. A typical bra consists of a chest band that wraps around the torso, supporting two breast cups that are held in place by shoulder straps. A bra usually fastens in the back, using a hook and eye fastener, although bras are available in a large range of styles and sizes, including front-fastening and backless designs. Some bras are designed for specific functions, such as nursing bras to facilitate breastfeeding or sports bras to minimize discomfort during exercise.
Underwear, underclothing, or undergarments are items of clothing worn beneath outer clothes, usually in direct contact with the skin, although they may comprise more than a single layer. They serve to keep outer clothing from being soiled or damaged by bodily excretions, to lessen the friction of outerwear against the skin, to shape the body, and to provide concealment or support for parts of it. In cold weather, long underwear is sometimes worn to provide additional warmth. Special types of undergarments have religious significance. Some items of clothing are designed as undergarments, while others, such as T-shirts and certain types of shorts, are appropriate both as underwear and outerwear. If made of suitable material or textile, some underwear can serve as nightwear or swimwear, and some undergarments are intended for sexual attraction or visual appeal.
An underwire bra is a brassiere that utilizes a thin, semi-circular strip of rigid material fitted inside the brassiere fabric to help lift, separate, shape, and support a woman's breasts. The wire may be made of metal, plastic, or resin. It is sewn into the bra fabric and under each cup, from the center gore to under the wearer's armpit. Many different brassiere designs incorporate an underwire, including shelf bras, demi bras, nursing bras, and bras built into other articles of clothing, such as tank tops, dresses and swimsuits.
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a female, the testicles in a male. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Physical growth—height and weight—accelerates in the first half of puberty and is completed when an adult body has been developed. Before puberty, the external sex organs, known as primary sexual characteristics, are sex characteristics that distinguish males and females. Puberty leads to sexual dimorphism through the development of the secondary sex characteristics, which further distinguish the sexes.
In Western society, since the 1960s, there has been a slow but steady trend towards bralessness among a number of women, especially millennials, who have expressed opposition to and are giving up wearing bras. In 2016, Allure magazine fashion director Rachael Wang wrote, "Going braless is as old as feminism, but it seems to be bubbling to the surface more recently as a direct response to Third Wave moments like #freethenipple hashtag campaign, increased trans-visibility like Caitlyn Jenner's Vanity Fair cover ... and Lena Dunham's show Girls."
