Victoria Beckham already posed once for Marc Jacobs's Spring ads [1], but the designer convinced her to go in front of the camera one more time — in the buff.

Posh joins [2] the likes of Hilary Swank, Dita Von Teese, Winona Ryder, Julianne Moore, and Christy Turlington by appearing undressed on a Marc Jacobs T-shirt to raise money for the Interdisciplinary Melanoma Cooperative Group at New York University. She said of the move:

Since we have moved to California, I have realized how important it is to practice safe sun for myself and to keep the skin of my three boys well protected as well. Skin cancer is a huge problem and I really wanted to help raise awareness by taking part in Marc's initiative.

The $35 tee goes on sale this week in Marc Jacobs boutiques.
