These pink dance ensembles were created by the famous costume designer Irene, who by this point in her career was the head costume supervisor at MGM studios. She had come to MGM several years previously to replace costume designer Adrian when he went to work for Universal Studios.
These costumes were first seen in the 1946 film Easy to Wed, a remake of an earlier film called Libeled Lady. The pieces appear on background singers and dancers for Lucille Ball’s production number, entitled “Continental Polka”, which can be viewed here.
The costumes, complete with feather headdresses, but minus the gloves, were used again in the 1948 film Easter Parade, where they were worn on background singers and dancers, as well as Judy Garland herself, playing the character of Hannah Brown.
