Fairly mild, but rather risque considering when it was made.
One scene, in which two characters start fighting, and then begin kissing passionately could be seen as implying a sexual encounter especially since they are in a room alone by themselves.
Some women wear fairly provocative attire for the time period. Example: Janet Leigh's dress reveals cleavage and Eleanor Parker reveals her legs in outfit with nylons.
At one point, a woman's upper back is visible as she changes behind a screen.
There are veiled innuendos throught this film. One character (it is implied) is the illegitimate son of a Baron.
