In 1907, a woman was arrested on a beach in Boston for wearing a one-piece swimsuit.
Annette Marie Sarah Kellermann was an Australian professional swimmer, vaudeville star, film actress, and writer.
Kellermann was one of the first women to wear a one-piece bathing costume, instead of the then-accepted pantaloons, and inspired others to follow her example. Kellerman's swimming costumes became so popular that she started her own fashion line of one-piece bathing suits. Kellermann helped popularize the sport of synchronised swimming, and authored a swimming manual. She appeared in several movies, usually with aquatic themes, and as the star of A Daughter of the Gods was the first major actress to appear nude in a Hollywood production. Kellermann was an advocate of health, fitness, and natural beauty throughout her life.
Kellermann advocated for the right of women to wear a one-piece bathing suit, which was controversial at the time. According to an Australian magazine, "In the early 1900s, women were expected to wear cumbersome dress and pantaloon combinations when swimming. In 1907, at the height of her popularity, Kellermann was arrested on Revere Beach, Massachusetts, for indecency – she was wearing one of her fitted one-piece costumes."
The popularity of her one-piece suits resulted in her own line of women's swimwear. The "Annette Kellermans", as they were known, were the first step to modern swimwear.
