Showgirl
A showgirl is a female performer in a theatrical revue who wears an exotic and revealing costume and in some shows may appear topless. Showgirls are usually dancers, sometimes performing as chorus girls, burlesque dancers or fan dancers, and many are classically trained with skills in ballet.
The French view the term showgirl as an American idiomatic expression. Some strip clubs and some strippers use the term showgirl as part of their business name.
