In 1956, Speedo first introduced nylon into swimwear, and in the 1970s, Speedo added elastane into their swimwear.

Women’s swimwear has undergone an unparalleled transformation

Sea bathing became popular as a recreational activity. Bathing in the sea provided health benefits for both women and men but immersing oneself completely was not seen as sufficiently feminine. Women would wear loose, open gowns similar to the chemise which were more comfortable to wear in the water when compared to more restrictive day clothes. The gown was made from linen with small lead weights sewn into each quarter of the dress to ensure the dress did not float up.

18th Century Swimwear

During the Victorian era, women wore bathing dresses with high necks, long sleeves, and knee-length skirts. Linen and wool fabrics were used with belts at the waist. Women would wear bloomer-like trousers under the bathing dress to maintain their modesty. Towards the end of the Victorian era, a one-piece garment became popular, where the blouse was attached to the trousers. Women wore a mid-calf-length skirt on top to divert attention from the wearer's figure.

19th Century Swimwear

In the 1910s, Jantzen was the leading producer of bathing suits. Jantzen first produced 'woollen suits' for rowing clubs, but its popularity cause Jantzen to market it to a wider audience. In 1921, Jantzen referred to the garment as a swimsuit. After the First World War, women’s swimwear trends began to differ across continents. American and European women wore knitted swimwear, but it tended to become misshapen when wet, jeopardising the modesty of the swimsuits.

The start of technological advancements in swimwear material

Lastex yarn was invented in 1931 and became a game-changer for swimwear. Lastex would often be combined with artificial fibres such as rayon resulting in a stretchy and shiny fabric that would hold its form in and out of the water. Swimsuits could now be produced in a much larger range of colours and prints. At the end of the 1940s, Christian Dior launched his New Look, which consisted of nipped-in waists and full skirts, which shifted the trend to feminine and hourglass figures for women.

Material advancements allowed for significant transformations in twentieth-century women’s swimwear. Swimming became a competitive sport, and women started to compete in the Olympics in 1912. Australian swimmer Anette Kellerman is credited with the modernization of female swimwear. She was invited to perform in front of the British Royal Family in 1905, but her swimsuit was prohibited as it was tight-fitting and showed the lower half of her legs. So she sewed black stockings onto her swimsuit.
