Indecent exposure
The standards of decency have varied over time. During the Victorian era, exposure of a woman's legs and arms was seen as indecent in much of the Western world. At formal occasions, hair was sometimes required to be covered with a hat or bonnet. As late as the 1930s, and sometimes the 1950s. both women and men were expected to bathe or swim in public places wearing bathing suits that covered above the waist. An adult woman exposing her navel was seen as indecent in parts of the West into the 1960s and 1970s. Moral values changed drastically during the 1990s and 2000s. This also changed the criteria for indecent exposure.
