Liv Ullmann in Shame (1968)
1968 was in the early days of film nudity, but Ullmann was a veteran by then. She did her first nude film scene in 1959, making her a true pioneer!
Here is the 1968 scene pictured in the film clip
And here she is in 1959 in Ung Flukt
Liv in 1959, damn. No wonder she was big.
