Lana, Queen of the Amazons (1964)

Lana skinny dips and then runs out of the pond fully nude as a man watches. Shown from a distance, we see breasts and bush very briefly and then her butt. The man walks to her as she puts on a loincloth and a flower neck piece that covers her breasts.

A topless female native, breasts visible, is shown wearing a loincloth and talking to different men in a couple of scenes.
