What's the easiest way for a celebrity to bring attention to a worthy cause? They could give impassioned, intelligent speeches, or work with politicians to make changes in public policy -- but it'd be way easier (and more effective) if they just took their clothes off.

That's the approach Victoria Beckham took when she wanted to raise awareness about skin cancer. She appears sans clothing on this "Protect the skin you're in" t-shirt, available at Marc Jacobs stores this week (and looks pretty darn good, if I do say so myself).

Posh isn't the only celeb who's adorned the Marc Jacobs cancer-fighting nudie tees. Previous models include Dita von Teese, Naomi Campbell, Winona Ryder and Julianne Moore.

For only about $35, you get a naked Posh t-shirt and help in the fight against cancer? Sounds like a bargain to me.
