Fini arrived in Paris in the early 1930s, where she became a self-taught artist. Her work frequently featured commanding figures of women, sphinxes, and eroticised self-portraits with billowing hair. She also depicted emasculated males, often drawing inspiration from the Renaissance paintings she observed in her youth. Her style utilised tightly rendered surfaces to present fantastical and otherworldly realities.

Throughout her career, Fini worked as a painter, designer, illustrator, and author. She once described her own extensive oeuvre as seditious, irregular, contradictory, and unacceptable to specialists of art, culture, logic, morality, and behaviour. Fini died in 1996, leaving behind a legacy of work that challenged conventional depictions of gender and power.
