The biggest difference in the 2013 Pirelli Calendar is that its subjects aren't nude. Photojournalist Steve McCurry shot this year's calendar in Rio de Janeiro and he said he wanted to "portray women who are sexy without being naked."
Those women include Adriana Lima — the first visibly pregnant woman to be depicted in the calendar — and fellow models Isabeli Fontana, at left, Liya Kebede, Karlie Kloss, Petra Nemcova, Hanaa Ben Abdesselem, Elisa Sednaoui, Kyleigh Kuhn, and Summer Rayne Oakes. Brazilian actress Sonia Braga and singer Marisa Monte will also appear in the calendar.
All of McCurry's subjects support charitable foundations, NGOs, and other humanitarian projects. Kloss, for example, promotes FEED with her Perfect 10 Cookies, and Kuhn is the founder of Twenty Four Suns, a company that supports artisans in Afghanistan. Nemcova auctioned off a trip to Brazil with tickets to the calendar's Nov. 27 gala there and donated the proceeds to the Happy Hearts Fund.
A look at the first images from what McCurry has called the "calendar of the soul" — plus a behind-the-scenes look at how it was made — right here in the gallery.
