I am pretty certain she was never actually naked in the movie. Just a tight zipped leather suit
I hate to shatter teenage illusions, but even the sexiest chocolate lover ages

Thankfully I can remember her when she could sing, before she discovered drugs (which destroyed her voice,) and Mick Jagger (who destroyed everything else.)
In the film, the zip did get lowered, but that was it; I felt like asking for my money back.
