All Ladies Do It (original Italian title: Così fan tutte) is a 1992 Italian comedy-drama directed by the provocative filmmaker Tinto Brass. The film explores the story of Diana, a woman who, after five years of marriage, discovers what she believes are the unexpected joys of adultery. In a controversial twist, she claims that betraying her husband might actually save their failing relationship rather than destroy it.

The film is a character study of marital dissatisfaction and sexual exploration, presented through Brass's signature erotic and visually stylized approach. While the IMDb rating of 5.2 suggests mixed reception, the film has developed a cult following among fans of European arthouse cinema and Brass's distinctive directorial style. The performances, particularly from the lead actress, capture the internal conflict and liberation of a woman challenging societal norms about fidelity.

Viewers interested in European cinema, relationship dramas with comedic elements, or Tinto Brass's body of work should watch All Ladies Do It online. The film offers a thought-provoking, if controversial, perspective on marriage and desire, set against the backdrop of early 1990s Italy. Its exploration of whether betrayal can paradoxically strengthen a relationship makes for engaging, conversation-starting viewing.
