The Grasshopper (1970)

Before Jacqueline Bisset made wet T-shirts go Hollywood in The Deep (1977), she starred in The Grasshopper (1970). It's the story of a good Canadian girl's corruption by the United States. She follows her boyfriend to L.A., then Las Vegas, where she becomes a showgirl and shows her girls in revealing costumes, before returning to L.A. and a life of prostitution. Jacqueline is not officially nude but comes so close you'll hop for joy.
