So Young, So Lovely, So Vicious (1975)

Unhappy with her father’s choice for a new mate, a young woman (Gloria Guida) sabotages her stepmother’s future in the crackling erotic drama Peccati di gioventù (1975). Silvio Amadio’s film was distributed domestically under the title So Young, So Lovely, So Vicious…, which is a perfect description of the achingly gorgeous, sadistically evil anti-heroine. Exploiting her stepmother’s Sapphic past and attempting to catch her in a variety of compromising positions, the fiendish young woman eventually grows so desperate that she resorts to drastic, disturbing measures. As detestable as her character is, it’s hard not to feel drawn to Guida. The tall blonde Italian bombshell is characteristically ravishing in her obligatory nude turns.
