How a scandalous arrest on a Boston beach changed women's swimwear forever
In short: Before the 1900s, women’s swimwear was designed for coverage, not movement. That changed when Australian swimmer Annette Kellerman introduced a form-fitting, sleeveless suit. Though her 1907 arrest for indecent exposure on a Boston beach remains uncorroborated, the resulting public outcry helped transform the one-piece into a global standard.
The modern one-piece swimsuit, initially termed a maillot, emerged in the mid-1900s. Annette Kellerman, who popularized the style, claimed she was arrested in 1907 for wearing a suit that exposed her arms, legs, and neck—a design she had adopted from England. While no independent evidence confirms this arrest, the story ignited a public debate that ultimately accelerated the acceptance of the style. By 1910, the look was common in parts of Europe, and it became the official attire for women at the 1912 Summer Olympics.
Despite its growing popularity, the Kellerman swimsuit faced significant resistance. Throughout the 1920s, some critics viewed it as the most offensive style available, leading to active censorship efforts. As late as 1943, images of the suit were used as evidence of indecency in the legal case Esquire v. Walker. Nevertheless, the garment gained cultural legitimacy through endorsements in publications like Harper's Bazaar, which praised its fit and beauty in 1920 and 1921, and its association with the increasingly respectable Miss America pageants.
Technological shifts in the 1920s and 1930s fundamentally altered the swimsuit's construction. As public interest moved from merely 'taking in the water' to sunbathing, designs became more decorative and body-conscious. The introduction of latex and nylon allowed for tighter, more flexible fits. In the modern era, the one-piece has evolved into a high-performance tool; professional athletes now use 'bodyskins'—engineered from textured fabrics that mimic sharkskin—to reduce water friction. Meanwhile, pop culture icons like the Baywatch red swimsuit have demonstrated that the one-piece can balance functional utility with iconic aesthetic appeal.
