A Behind-the-Scenes Look at the Soulful 2013 Pirelli Calendar

Before the 2013 Pirelli Calendar is introduced to the world next week, we're taking a behind-the-scenes look at how it was made.

The biggest difference in this year's calendar, shot in Rio de Janeiro, Brazil, is that its subjects aren't nude. Photojournalist Steve McCurry shot the calendar this year, and he said he wanted to "portray women who are sexy without being naked."

This year 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.
