What really struck me the most, and many others also commented on the same, was the 'suggestive nature' of the song. Her coquettish behavior would definitely have been more ramped up pre-code.
I was also struck by her appearance in her dressing room. She is fully clothed, for sure, but the light shade of the dress fabric and the way it fits her body seems rather risqué for the time (but that might just be me.)
