Gaiety Girls were the chorus girls in Edwardian musical comedies, beginning in the 1890s at the Gaiety Theatre, London, in the shows produced by George Edwardes. The popularity of this genre of musical theatre depended, in part, on the beautiful dancing corps of "Gaiety Girls" appearing onstage in bathing attire and in the latest fashions. The 1890s Gaiety Girls were respectable, elegant young ladies, unlike the corseted actresses from London's earlier musical burlesques. Later, even the stars of these musical comedies were referred to as Gaiety Girls.
An American newspaper reviewing A Gaiety Girl in 1894 explained the importance of the Gaiety Girls: "The piece is a mixture of pretty girls, English humor, singing, dancing and bathing machines and dresses of the English fashion. The dancing is a special feature of the performance, English burlesques giving much more attention to that feature of their attractiveness than the American entertainments of the same grade do." Many of the best-known London couturiers designed costumes for stage productions by the 1890s. The illustrated periodicals were eager to publish photographs of the actresses in the latest stage hits, and so the theatre became an excellent way for clothiers to publicise their latest fashions.
Gaiety girls were polite, well-behaved young women. They became a popular attraction and a symbol of ideal womanhood. Edwardes arranged with Romano's Restaurant, on the Strand, for his girls to dine there at half-price. It was good exposure for the girls and made Romano's the centre of London's night-life. Many of the Gaiety Girls, such as Marie Studholme, Ellaline Terriss, Lily Elsie, Cicely Courtneidge, Gladys Cooper, Phyllis Dare, Zena Dare, Mabel Love, Evelyn Laye, Jennie McNulty, Gaby Deslys, Camille Clifford, Gabrielle Ray, Sylvia Grey and Constance Collier, later enjoyed substantial acting careers. One Gaiety Girl, Mabel Russell, became a Member of Parliament.
