Who is Bianca Jagger?
Born in Nicaragua, she studied in Paris and married Mick Jagger in 1971. Through the 1970s she was one of the most photographed women in the world. Since the 1980s she has worked as a human rights and environmental campaigner, and founded a human rights foundation in her name.
What did she wear to her wedding?
At her wedding in Saint-Tropez in 1971 she wore a white Yves Saint Laurent tailored jacket, cut low with nothing underneath, over a long skirt, with a wide-brimmed hat and veil. Rejecting the traditional gown for a suit was radical, and it is still a reference for modern brides who want tailoring.
What happened at Studio 54?
For her birthday party at the New York nightclub in 1977, she rode onto the dance floor on a white horse, in a flowing red dress by Halston. The photograph became the defining image of disco-era excess. Halston, a close friend, dressed her in fluid jersey, halter necks and kaftans.
Why does she still matter?
She proved that women’s tailoring could be sexier than a dress, years before power dressing, and her mix of suits, canes, hats and bare skin still appears on runways. Saint Laurent’s Le Smoking and her wedding suit are part of the same story. See 1970s fashion.
