A showgirl is a female dancer or performer in a stage entertainment show intended to showcase the performer's physical attributes, typically by way of revealing clothing or even toplessness or nudity. Showgirls are often associated with Latin music and dance, particularly samba.
The term showgirl is sometimes applied to a promotional model employed in trade fairs and car shows.
Showgirls date back to the late 1800s in Parisian music halls and cabarets such as the Moulin Rouge, Le Lido, and the Folies Bergère.
The Las Vegas showgirl
Showgirls were presented in Las Vegas in 1952 as the opening and closing act for Las Vegas headliners, sometimes dancing around the headliner. They were introduced at the Sands Casino for a show with Danny Thomas. In 1957 Minsky's Follies took the stage at the Desert Inn giving birth to the topless showgirl in Vegas. This was followed by a long-running The Lido de Paris at the Stardust Casino that ran for 31 years.
