Project Runway‘s hosts are really making it work as Heidi Klum and Michael Kors team up with Saks Fifth Avenue for their annual Key to the Cure campaign to raise money for women’s cancer charities. Kors has created a limited-edition T-shirt that the supermodel will wear in a national public service announcement featured in major fashion and lifestyle magazines through the months of September and October. As the campaign’s ambassador, Heidi joins the ranks of Gwyneth Paltrow, Nicole Kidman, Hilary Swank, Charlize Theron and more who have all held the honor in previous years. The Michael Kors limited-edition T-shirts are available at and Saks Fifth Avenue stores for $40, with $34 from the sale of each tee benefitting local women’s cancer charities. Or wait until October 15-18, when Saks will donate 2% of sales (up to $250,000) from the shopping weekend to local and national women’s cancer organizations and research centers.
