Some of the country’s most powerful political, business and fashion leaders have gathered in Sydney to farewell fashion mogul Carla Zampatti.

Thursday’s official farewell was what Zampatti’s daughter described as “the best-dressed funeral”, with guests adorned in her iconic designs, there to celebrate the 78-year-old’s life and work.

After founding her eponymous label in 1965, the Italian-Australian designer was remembered as a trailblazer in the industry, bringing practical, fashion-forward designs to the working women of Australia.

Zampatti’s pieces have been worn by everyone from Nicole Kidman and Cate Blanchett to former prime minister Julia Gillard and Denmark’s Princess Mary.

St Mary’s Cathedral was filled with Zampatti’s famous friends and fans, as well as hundreds of white orchids.

Attendees included former governor-general Quentin Bryce, who spoke before Zampatti’s three children.

Julie Bishop, and former PMs Malcolm Turnbull and John Howard attended with their wives, Lucy Turnbull and Janette Howard.

Television presenters, and long-time Zampatti wearers, Melissa Doyle and Natalie Barr, were also present.
