Sean Avery Gets Naked for Marc Jacobs

New York Rangers player Sean Avery shed his padding to advocate skin cancer prevention for designer Marc Jacobs.

Standing fully nude, Avery covers only his genitals for a T-shirt that says, "Protect Your Largest Organ," referring to the skin. The shirt is part of the Protect the Skin You're In campaign; other celebrity participants include Heidi Klum, Rufus Wainwright, and Victoria Beckham.

Jacobs released the images of Avery and others on colored T-shirts to raise money for medical research at the New York University Cancer Institute at NYU Langone Medical Center. According to its Facebook page, the fund-raising effort has already raised more than $1 million for NYU's School of Medicine's Interdisciplinary Melanoma Cooperative Group.
