It’s safe to say Bianca Jagger has led a very full life. The style icon, born Blanca Pérez-Mora Macías in Managua, Nicaragua, has been cemented in the public imagination as the fabulous woman who rode into Studio 54 on a horse. But the fashion model and human rights defender has remained booked and busy since her heyday as a famed ’70s socialite.

Currently, she serves as the chair of her Bianca Jagger Human Rights Foundation. She’s also a member of the executive director’s leadership council of Amnesty International U.S., a goodwill ambassador to the Council of Europe, and a trustee of the Amazon Charitable Trust. The latter cause seems to capture Jagger’s spirit the most. Speaking from her home in the U.K., Jagger tells W about her early memories of walking through the rainforest with her mother in her home country as a child, and how the scent of the wild orchids there permanently influenced her relationship with fragrance.

Now Jagger is the latest star of YSL Beauty’s very feminine Libre Flowers & Flames perfume, which has notes of coco palm tree flower, lily, orange blossom, and vanilla. The partnership with YSL Beauty is a natural one—fashion fans will recall the famous Yves Saint Laurent tailored two-piece bridal suit she wore to marry Rolling Stones frontman Mick Jagger in a Saint-Tropez courthouse in 1971. Below, Bianca Jagger reflects on the key to aging well, the qualities that make a woman beautiful, and what her mother taught her about perfume.
