Marisa Miller is showing off her beach-worthy birthday suit in the name of a charitable cause.

The 32-year-old who is best known for her scantily-clad modeling stints on the covers of Victoria's Secret catalogs and the Sports Illustrated swimsuit edition, is starring in the new ad for Marc Jacobs' skin cancer awareness campaign entitled, "Protect The Skin You're In."

In the campaign, voluminous beachy waves barely cover Miller's D cup-sized assets, while the careful placement of a hand prevents the image from going X-rated.

"I thought wearing my Chucks was better than heels, right?" the model quips on her blog.

"The skate deck I'm holding is a really cool vintage deck from Santa Cruz Skateboards. It was made over to promote the charity -- but maybe one day I can post the original with the SC skate logos :)," adds the longtime surfer and skateboard enthusiast.

The provocative image is printed on yellow T-shirts that will sell at Marc Jacobs boutiques worldwide, with proceeds benefiting the NYU Cancer Institute at New York's Langone Medical Center.

Miller joins the ranks of previous campaign models, who have included Heidi Klum, Dita Von Teese, Naomi Campbell, Helena Christensen and Victoria Beckham.

However, cancer awareness advocacy is nothing new to the Santa Cruz, California native, as Miller has been an ambassador for The American Cancer Society's Making Strides Against Breast Cancer campaign since 2009, with proceeds from her online store benefiting the charity. Miller is also a supporter of the Young Survival Coalition.

We expect that the bright tees will fly off shelves -- just don't try wearing it in Dubai.

And clearly, Marc Jacobs has an affinity for going nude.
