Goodtime Girls (1980)

Four young ladies--levelheaded Edith, girl-next-door Betty, dumb-blonde Loretta, and stuckup Camille--are forced to share a one-room apartment in Washington, D.C. during World War II. The four learn to live together and help one another, and they took jobs to help in the war effort. The Coolidges were their landlords, Frankie was their cab-driver buddy, and Benny was a pal of Frankie's.
