Isabelle Huppert in nude scene from The Bedroom Window which was released in 1987. She shows us her tits and ass. There is not much other real nudity but Isabelle Huppert looks quite sexy in that underwear.
Also Elizabeth McGovern naked in The Bedroom Window. So Elizabeth McGovern is not shy and she demonstrating her boobs.
I am looking for a similar scene, where the girl from the window asks for help, and for this she undresses from the window of the building (to get attention), there is a child in a building and in the street a beggar. She asked for help because in another room they were beating someone and the neighbors below believed they were having sex (because of the noises and blows)
