Now, with New York Fashion Week approaching, Ms. Wintour has roped in Sarah Jessica Parker to help with a second fund-raiser on Sept. 9 at Charles Nolan's West 27th Street studio, according to British Vogue.

In the spirit of Fashion Week, the fund-raiser will include a mini-fashion show, with designs donated by Diane von Furstenberg, Marc Jacobs, Zac Posen, Proenza Schouler, and Narciso Rodriguez making their way down the runway.

This election year isn't the first time that Ms. Wintour has backed a Democratic candidate.

In 2004, according to Women's Wear Daily (subscription required), Ms. Wintour donated $2,000 to the John Kerry campaign. This was the same year that other fashion figures like Michael Kors, Cynthia Rowley, Kenneth Cole, Marc Bouwer and Ms. von Furstenberg also publicly backed the candidate.

This is also the final disappointment for Hillary Clinton, who in January backed out of a Vogue cover in fear of appearing too alluring, thereby angering Ms. Wintour.

In her February editor's letter, Ms. Wintour wrote, "Imagine my amazement, then, when I learned that Hillary Clinton, our only female president hopeful, had decided to steer clear of our pages at this point in her campaign for fear of looking too feminine. The notion that a contemporary woman must look mannish in order to be taken seriously as a seeker of power is frankly dismaying."

It seems the Obamas have no such reservations about having the glitzy fashion world behind them.
