This scene is evidence for my contention that redhaired actresses are more likely than blondes or brunettes to do full-frontal nudity.
The first two, already mentioned, were Julie Andrews and Kathy Bates.
Three leaped immediately to mind.
In the Robert Altman movie Short Cuts her character takes off a skirt to iron it, and her husband is upset that she has no panties on.
Altman wanted to use nudity realistically.
Its full frontal as well.
The third: Emma Thompson in The Tall Guy.
Anyway, these were relatively mild topless scenes.
