During the late 19th century, corsets became smaller, less bulky and more constricting and were gradually supplanted by the brassiere, first patented in the 20th century by Mary Phelps Jacob. When the First World War broke out, women found themselves filling in men's work roles, creating a demand for more practical undergarments. Manufacturers began to use lighter and more breathable fabrics. In 1935, brassières were updated with padded cups to flatter small breasts and three years later underwire bras were introduced that gave a protruding bustline. There was also a return to a small waist achieved with girdles. The 1940s woman was thin, but had curvaceous hips and breasts that were pointy and shapely. In the 1960s, the female silhouette was liberated along with social mores. The look was adolescent breasts, slim hips, and extreme thinness. André Courrèges was the first to make a fashion statement out of the youth culture when his 1965 collection presented androgynous figures and the image of a modern woman comfortable with her own body.
