In the decades that followed, the seaside dress code loosened up considerably. In 1907, Australian swimmer and silent-film star Annette Kellerman—a vocal advocate of more hydrodynamic swimwear—was charged with indecent exposure for appearing on Boston's Revere Beach in a form-fitting, sleeveless tank suit. The ensuing high-profile legal scuffle led beaches across the nation to relax their swimwear restrictions. By 1915, American women commonly wore one-piece knitted maillots.
