A t-shirt designed by Karl Lagerfeld, modeled by 2008 ambassador Gwyneth Paltrow , and benefiting charity? I'll take it. This Karl Lagerfeld for Saks Fifth Avenue Key to the Cure T-Shirt  ($40), sold exclusively at Saks, is not only super stylish (leave it to Karl to put a caricature of himself on the back), but it also won't put a major dent in your wallet. Over $35 of your purchase will go to the Entertainment Industry Foundation's Women's Cancer Research Fund. Fashion philanthropy — fabulous!
