Nothing says stop, look and listen like a naked Sports Illustrated model, ey? Marc Jacobs — never one to shy away from nudity himself — knows this. 'Tis why the fashion designer has enlisted the help of former Victoria's Secret hottie Marisa Miller to promote awareness around a very serious issue: skin cancer. Ms. Miller, the third sexiest woman in the world according to FHM magazine, has joined the ranks of Victoria Beckham, Dita von Teese, Heidi Klum, Helena Christensen and Naomi Campbell to strip down for Marc Jacobs' Protect The Skin You're In skin cancer awareness initiative. T-shirts featuring a naked Marisa Miller will be available in Marc Jacobs stores with all proceeds being donated to the NYU Cancer Institute. Marisa says: "We have so many great products now that there's no reason to put yourself at risk for a tan." Exactly. Now, you heard the lady. Slip, slap, slop. And make sure it's SPF 30+.
