Now the magazine's long-standing creative director is set to tell her story after signing a rumoured $1.2million deal with Random House.
The 70-year-old, who is hailed by many in the industry as 'the world's greatest living stylist', is believed to have enlisted fellow Vogue staffer Michael Roberts as co-writer.

The news follows months of rumours that Ms Wintour has a memoir in the works - whether they were misplaced, or the two tomes will go head-to-head remains to be seen.
News that Ms Coddington had a memoir first emerged last year, in an interview with WWD. She told the trade title: 'I’m hoping it’s going to be very rich in fashion history. It’s more than just about me.'
But it is the stylist's own history that is likely to be the most riveting part.
Born in Wales to hotelier parents, she moved to London at the age of 17, where she began modelling for legendary photographers including Norman Parkinson.
But her career was cut short at the age of 26 after here eyelid was badly damaged in a car crash.
Unable to model, she used her knowledge of the fashion industry to carve a role as a stylist, eventually landing a position as a junior fashion editor at British Vogue.
She moved to the fashion glossy's U.S. counterpart when Ms Wintour took over as editor in 1988, and the pair have worked alongside one another ever since.
But as The September Issue reveals, their relationship is not an easy one.
In one scene, Ms Coddington is devastated when the editrice rejects a lavish $35,000 shoot. Others show their barbed repartee, which actually appears to give the pair some pleasure.
After one such tense moment in the documentary, she admits to the camera crew: 'I love to talk budgets with Anna in front of you guys. She hates it. It's a sure way to get the budget up.'
