Anna Wintour has topped the fashion names on Forbes' 100 Most Powerful Women list.

The American Vogue editor-in-chief and artistic director of Condé Nast has been placed at number 39 on this year's list - two places higher than in 2013 - following her fundraising work for the Anna Wintour Costume Centre and President Obama's re-election campaign.

Anna, 64, beat designers Diane Von Furstenberg, who ranked in 68th place, Miuccia Prada in 75th and Tory Burch in 79th as well as supermodel Gisele Bundchen, who has an estimated wealth of $42million.

Also on the list in 43rd place is Spanx creator Sara Blakely who made history after turning her $5,000 life savings into the billion dollar brand, becoming the world's first self-made female billionaire.

Following in the footsteps of Bill Gates and Warren Buffet, Sara has also joined the Giving Pledge, vowing to donate at least half of her earnings to charity.

Beyonce, Shakira, Oprah Winfrey, Angelina Jolie and Sofia Vergara also made it onto the list, which was topped by the German Chancellor, Angela Merkel.
