What is the name of Gianni Versace's sister?

Gianni Versace’s sister was Donatella Versace.

Donatella Francesca Versace was born in 1955 in Reggio Calabria, Italy, and grew up in the same fashion-oriented family as Gianni. Their mother, Francesca, was a dressmaker who ran a small boutique, giving both siblings an early connection to clothing and design.

Donatella worked closely with Gianni after joining him and their brother Santo in Milan. She became a creative collaborator, helping shape Versace’s image, styling, accessories, and later the Versus diffusion line. Gianni regarded her as both a trusted partner and a muse; he dedicated his 1989 Blonde fragrance to her.

A common mix-up is Santo Versace, who was Gianni’s brother, not his sister. The family also included an older sister, Tina, who died as a child. After Gianni’s murder in 1997, Donatella succeeded him as Versace’s creative director and became the public face of the brand’s next era.
