The term 'Bathing Beauty' is a phrase used to describe a woman who is attractive and often photographed in a swimsuit or other beachwear. The term is also associated with the pinup art style, which was popular in the 1940s and 1950s. Pinup art typically featured women in provocative poses, often wearing swimsuits or lingerie. The term 'pinup' is derived from the idea of a woman being pinned up on a wall as a decoration.
