There was no single inventor of the bra. Breast-support garments developed over many decades as designers responded to changing clothing, body ideals, manufacturing methods, and demands for comfort and movement. Mary Phelps Jacob—later known as Caresse Crosby—is the name most often associated with the invention because her 1914 patent described a lightweight, backless, boneless brassiere suited to low-backed dresses. But her design was an important modern milestone, not the first attempt to support the breasts.
Earlier inventions by Henry S. Lesher, Marie Tucek, and Herminie Cadolle had already explored ways to separate bust support from the restrictive corset. Later, the bra became a tool for flattening, lifting, enlarging, smoothing, and stabilizing the body—and, with the 1977 Jogbra, for making exercise more comfortable.
The short answer: who invented the bra?
The most accurate answer depends on what “invented the bra” means:
| Milestone | Person or company | Why it matters |
|---|---|---|
| 1859 | Henry S. Lesher | Patented a breast-pad and perspiration-shield that included breast support, although it was not a modern bra. |
| 1889 and after | Herminie Cadolle | Helped develop a breast-supporting upper section that could eventually be separated from the corset. |
| 1893 | Marie Tucek | Patented a breast supporter with two pockets, shoulder straps, and adjustable fasteners—one of the closest nineteenth-century structural precursors. |
| 1914 | Mary Phelps Jacob, later Caresse Crosby | Patented a flexible, backless, boneless brassiere designed for fashionable low-backed clothing. |
| 1977–1979 | Hinda Miller, Lisa Lindahl, and Polly Smith | Developed the Jogbra, generally recognized by the Smithsonian as the first modern sports bra. |
So the best one-sentence conclusion is: Mary Phelps Jacob did not invent breast support from nothing, but her 1914 backless brassiere was a decisive modern design in the long transition away from the corset.

Before bras: how corsets supported and shaped the body
For much of the nineteenth century, fashionable Western dress relied on corsets, also called stays. These garments did not support the breasts in the same focused way as a modern bra. Instead, they shaped the entire torso through a combination of tight construction, steel or other rigid boning, lacing, and carefully engineered panels.
The corset compressed the waist, supported the bust indirectly, and created the hourglass outline demanded by contemporary fashion. As the Metropolitan Museum of Art’s history of nineteenth-century corsets shows, corsetry was a highly technical form of clothing construction rather than merely a simple undergarment.
That distinction matters. The bra did not suddenly replace an identical earlier garment. It emerged from a changing foundation-garment system in which corsets, corset covers, bust supporters, girdles, bandeaus, and bras could coexist. Different garments suited different bodies, occasions, social expectations, and silhouettes.
The nineteenth-century precursors
Henry Lesher’s 1859 breast-pad
One early patent in the story belongs to Henry S. Lesher, who received a U.S. patent in 1859 for a “breast-pad and perspiration-shield.” The invention combined breast pads with underarm shields and elastic connections.

Its purpose already reveals that breast-support garments served several functions at once. The patent described support, a more symmetrical appearance, and protection for clothing from perspiration. It was not a modern bra with separate cups, a conventional band, and standardized sizing, but it demonstrates that inventors were addressing breast support separately from the full corset before the twentieth century.
Marie Tucek’s 1893 breast supporter
Marie Tucek’s 1893 U.S. patent is a closer structural precursor to the modern bra. Her “breast supporter” was intended to take the place of the usual corset, particularly under loose, Empire-style dresses.
The design included two breast pockets, shoulder straps that crossed at the back, and adjustable hooks and lacing. Those features make it recognizably bra-like: the breasts were supported individually, the garment was held up by shoulder straps, and the fit could be adjusted.
However, a patent does not prove that an invention became a successful, widely available commercial product. Tucek’s design is historically important as an early documented concept, but it should not automatically be described as the direct commercial ancestor of every later bra.
Herminie Cadolle and the separation from the corset
French designer Herminie Cadolle represents another essential branch of the story. The House of Cadolle exhibited an early form of the modern bra at the 1889 International Exhibition in Paris, according to the Victoria and Albert Museum.

Cadolle’s design initially formed the upper part of a larger corset system. Over time, however, the bust-supporting section was separated and sold on its own. That change was conceptually important: it treated breast support and waist control as two different design problems.
The independent bra therefore did not appear only because one inventor had a sudden idea. It grew from a gradual reorganization of women’s underwear.
Mary Phelps Jacob’s 1914 patent
Mary Phelps Jacob filed her U.S. brassiere patent on February 12, 1914. The patent was granted and published on November 3 of that year. It is the milestone most commonly cited when people ask who invented the bra.
Jacob’s design addressed a very specific problem: conventional corsets and corset-cover arrangements could interfere with low-backed evening dresses. Her brassiere was designed without a back, without rigid bones, and with fabric panels cut on the bias. It was lightweight and flexible rather than a stiff, waist-shaping foundation garment.
The patent emphasized several practical advantages:
- It did not interfere with a low-backed evening gown.
- It avoided rigid boning.
- It could be made in relatively few sizes.
- It was intended to be comfortable and cool beneath sheer clothing.
- Its flexible construction was suitable for movement, including activities such as tennis.
These details explain why Jacob’s design mattered. It was not simply a smaller corset. It offered bust shaping and support while leaving the waist substantially freer and making fewer demands on the back of a dress.
The famous handkerchief story
The familiar story says that Jacob improvised her first brassiere from two handkerchiefs, ribbon, and cord after a corset spoiled the line of a sheer evening gown. The anecdote has become a standard part of the bra’s origin story.

The primary document establishes what Jacob formally claimed: a backless, boneless brassiere designed for comfort, flexibility, and compatibility with low-cut clothing. It does not by itself prove every detail of the later anecdote.
Jacob eventually sold the patent to the Warner Brothers Corset Company. Her design became historically influential, but even the Metropolitan Museum of Art describes her contribution in the context of earlier brassiere-like garments. Calling her the inventor of the modern brassiere is more accurate than calling her the inventor of the first breast-support garment ever made.

Why the bra did not immediately replace the corset
The 1914 patent did not cause every woman to abandon corsetry overnight. For decades, corsets, girdles, bandeaus, and bras continued to serve different purposes.
Adoption depended on fashion, class, body shape, occasion, and personal preference. A woman might wear a corset or girdle to create a particular waistline, a bandeau to flatten the bust beneath a fashionable dress, or a bra for lighter support and greater freedom of movement. Foundation garments were not interchangeable simply because a new patent existed.

The 1920s: the bra that flattened rather than lifted
In the 1920s, fashionable clothing favored a straighter, more column-like silhouette. The desired torso was less curving than it had been in the nineteenth century, and the bra adapted accordingly.
The bandeau brassiere, often anchored by shoulder straps, was designed less to lift and project the breasts than to suppress or flatten them. This is one of the clearest demonstrations that a bra’s purpose is determined by the surrounding fashion. The same basic category of garment could support a fuller bust in one decade and minimize it in another.
Across its history, the bra has been designed to:
- Flatten or minimize the bust.
- Lift and separate the breasts.
- Create cleavage.
- Increase apparent volume through padding.
- Smooth the body beneath clothing.
- Reduce movement during physical activity.
- Provide modesty or concealment.
“Support” is therefore only part of the story. The bra has also been an instrument for constructing the outline that clothes were designed to display.

Standardized sizing and the commercial bra
As bras became mass-market garments, manufacturers needed ways to produce and sell them in graded sizes rather than making each garment individually.
Later patent literature records that S.H. Camp and Company introduced alphabetic cup labels—A, B, C, and D—in 1932. The original system did not necessarily mean what modern shoppers assume today; it described aspects of breast shape or pendulousness rather than a universal measurement of cup volume.
Band sizing became more common in the 1940s. Together, band and cup measurements allowed manufacturers to offer a more systematic range of fits, helping transform the bra from a relatively simple bust supporter into an engineered, mass-produced garment.

It is usually suitable for women with smaller busts to wear, and this sport bra runs small. For customers who want to wear loose fitting, it is recommended to order a one size larger bra for a comfortable and relaxed wearing experience.
Modern sizing still has important limitations. A cup letter does not represent a fixed volume independently of the band. A C cup in one band size is not equivalent in volume to a C cup in every other band size, and labels can vary among manufacturers and countries. The modern bra is commercially standardized, but its sizing is not one globally universal scientific language.
The 1940s and 1950s: shaping the “sweater girl” silhouette
By the 1940s and 1950s, bras were increasingly used to construct a pronounced, projected bust. The bullet bra became a characteristic mid-century form, creating a pointed outline through structured cups, seams, and shaping.
Popular culture helped associate this look with the “sweater girl”: a fitted, highly visible bust silhouette that clothing was designed to emphasize. The bra was no longer merely a device for holding the body in place. It helped produce the body outline itself.
Padding, molded cups, underwires, elastic, and structured fabrics gave designers and wearers ways to manipulate the relationship between the natural body and the fashionable body. In different periods, the same technologies could minimize, enlarge, lift, separate, smooth, or sharply project.
Stretch fabrics and the pursuit of comfort
New fibers and manufacturing methods changed what bras could do. Synthetic fabrics such as nylon made lighter, smoother, and more easily manufactured lingerie possible. The arrival of Lycra in the 1960s expanded the use of stretch in body-shaping garments, allowing close-fitting designs to move more readily with the body.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.The sports bra: when movement became the central problem
The sports bra emerged from a problem ordinary bras were not designed to solve. During running, aerobics, and other high-impact activities, many women experienced discomfort, soreness, chafing, slipping straps, embarrassment, and hardware that poked or shifted.
Women’s participation in athletics expanded substantially after Title IX in the United States, increasing the need for clothing designed around active movement rather than a static posture. The question was no longer simply how to create a particular shape beneath a dress. It was how to reduce uncomfortable breast movement while allowing the wearer to exercise.
Hinda Miller, Lisa Lindahl, and Polly Smith developed the Jogbra in the late 1970s. According to the Smithsonian’s National Museum of American History, early prototypes were made by sewing together men’s athletic supporters. The three inventors formed Jogbra, Inc. in 1977, and later received U.S. Patent 4,174,717 for an athletic brassiere on November 20, 1979.

The Smithsonian identifies the Jogbra as the first example of what became generally known as the sports bra. Its importance was not primarily aesthetic. It treated breast motion as an athletic-design problem and helped make running and other impact sports more comfortable and accessible.
Why was the bra invented?
There is no single answer because the purpose changed over time.
- To reduce reliance on the corset: Early breast supporters sought to support the bust without using a full, waist-constricting foundation garment.
- To suit changing fashions: Jacob’s design worked with low-backed evening clothes; 1920s bandeaus created a flatter torso; 1950s bras produced a more projected one.
- To improve comfort and mobility: Lightweight, flexible, boneless designs addressed the weight and restriction of corsetry.
- To enable mass production: Cup and band systems allowed manufacturers to sell graded sizes to a wider market.
- To control movement during exercise: The Jogbra responded to soreness, chafing, slipping, and discomfort during running and aerobics.
- To shape the body for presentation: Bras have been used to minimize, flatten, lift, enlarge, separate, smooth, and stylize the bust according to changing ideals.

Frequently Asked Questions
Did Mary Phelps Jacob invent the first bra?
No. Earlier breast-support garments and patents existed, including Henry S. Lesher’s 1859 breast-pad, Marie Tucek’s 1893 breast supporter, and Herminie Cadolle’s late-nineteenth-century work. Jacob’s importance lies in her 1914 patent for a backless, boneless brassiere that addressed modern clothing and comfort problems.
What was the bra originally invented for?
Its purpose varied by design and period. Early versions sought to support the breasts without a full corset; Jacob’s version was designed to work beneath low-backed clothing; later bras flattened or projected the bust; and the Jogbra was created to reduce discomfort and movement during exercise.
When was the modern bra patented?
Mary Phelps Jacob filed her U.S. brassiere patent on February 12, 1914. It was granted and published on November 3, 1914.
Who invented the sports bra?
Hinda Miller, Lisa Lindahl, and Polly Smith developed the Jogbra in 1977. They later received U.S. Patent 4,174,717 for an athletic brassiere on November 20, 1979.
Are bra cup sizes universal?
No. Cup letters depend on the band size and can vary between brands, sizing systems, and countries. A letter such as C does not represent one universal breast volume.

The Bottom Line
The bra was not invented by one person for one purpose. It evolved from corsets and earlier breast supporters as fashion demanded different silhouettes and as women sought lighter, more mobile clothing. Mary Phelps Jacob’s 1914 patent is the key modern milestone, while the 1977 Jogbra extended the garment’s purpose from shaping the body beneath clothing to supporting it during movement.
