Her French mother and Iranian father owned a house on Rue de Verdun in Le Vésinet, where Alvina attended the Lycée Alain.
The film included a scene of the seventeen-year-old Alvina's distantly-shot frontal nudity, albeit the actress was playing a fourteen-year-old character.
Alvina appeared regularly on the French screen, both cinema and television, throughout the 1970s chiefly in nymphet roles, working with such directors as Gérard Blain, Jacques Doniol-Valcroze, and Alain Robbe-Grillet, Alvina's highest career profile probably being afforded by the Robbe-Grillet films Glissements progressifs du plaisir (1974) and Le Jeu avec le feu (fr) (1975).
Then she joined the group Ici Paris, who had several singles released in 1980–83 and also a 1982 album, to replace Marie Alcaraz as lead singer and frontwoman.
Around the time of her 1984 marriage, Alvina evidently retired from the entertainment world and did not re-emerge till 1995, when she resumed her acting career with the first of a series of occasional screen appearances.
