To raise money for breast-cancer research, Seventeen Magazine asked some of our favorite stars—including Reese Witherspoon, Sarah Jessica Parker, Alicia Keyes, and Hilary Duff—to hand over their favorite handbags to be auctioned off on eBay. All of the proceeds from the auction, which began yesterday and runs through Sept. 23, will be donated to the American Breast Cancer Foundation, the American Cancer Society, and the Susan G. Komen Foundation. Here's a look at some of the fabulous bags and their former celebrity owners.
