She belongs to Film Noir...

 First of all you have to understand in which context the Femme Fatale develops! 
                               Her universe is the Film Noir world. 

The term "Film Noir" was given by French films critics. In 1946 Nino Franck was the first to use this term.

 They wanted to illustrate the trend of dark scenario during the Cold War. This time period was marked by insecurities, tensions and the threat of nuclear weapons. They also wanted to counter-balance the joviality of the Hollywood's musicals.

 Film Noir was a style of classic Black and White American films that started in the 1940's.

They dealt with the theme of murder, violence, betrayal, greedy purpose and they never propose happy endings.

The story is usually built around a cynical and disillusioned male character who met a beautiful, sexual, dangerous and ambitious female character who led him to his ruin.

 This woman is the well-know Femme Fatale!
