3 Women (1977) on Netflix

Pinky is an awkward adolescent who starts work at a spa in the California desert. She becomes overly attached to fellow spa attendant, Millie when she becomes Millie's room-mate. Millie is a lonely outcast who desperately tries to win attention with constant up-beat chatter. They hang out at a bar owned by a strange pregnant artist and her has-been cowboy husband. After two emotional crises, the three women steal and trade personalities until they settle into a new family unit that seems to give each woman what she was searching for.
