Irene Galitzine, Italy’s “fashion princess” whose gowns clothed Jacqueline Kennedy, Sophia Loren and Audrey Hepburn, died on Friday, a spokesman for the national fashion association told Reuters. She was 90.

Galitzine, whose design house became one of the hot labels during Rome’s “Hollywood on the Tiber” fashion heyday in the 1960s, died at her home in Italy’s capital, Ansa news agency said.

The cause of death was not immediately known.
