October is National Breast Cancer Awareness Month, and our friends at Shopbop are doing their part to contribute to the cause. Currently on sale are celebrity-designed pink tees ($88 each), half of whose proceeds go to Breast Cancer Network of Strength. Sophia Bush (left), Hilary Duff (center), Nicky Hilton (right), Jaime King, Cindy Crawford, and Denise Richards have all lent their artistic talent out of the goodness of their hearts. Now it's your turn to buy the tee you love out of the goodness of your heart.
