I saw it in 2000’s on TV. Probably, American or German film. In color.
A man uses his girlfriend, forcing her to sleep with influential people, tapes conversations with them for further blackmail. She waits for them to be together, but when she realizes that he does not love her, everyone loses their meaning. At the end of the film, she dances with everyone with whom she was in bed at a ball, and then leaves in the night without shoes. When other women talk about her, they note that her shoes are too gold.
