Outrageous! (1977)

Robin Turner is a gay hairdresser. He hates his job. He loves old movies and will do his customers' hair in the style of an iconic movie star if they'll let him, and even if they don't. At his apartment, he is harboring his medically diagnosed schizophrenic friend, Liza Connors, who can no longer stand being institutionalized. After Liza convinces Robin to attend a drag ball dressed as 'Tallulah Bankhead' (qv), Robin begins to feel liberated. On Liza's further urging, Robin accepts a local club's offer to work as a female impersonator, he doing his own singing unlike most drag queens. As he progresses with his female impersonation work to great aplomb, he takes a shot at making it big in New York City. The money will have to come in since despite medical warnings to her not to do it, Liza has become pregnant (not Robin's baby), she deciding to have and keep the baby.
