Kate Upton bared it all for a cancer campaign she announced on Wednesday.

The naked image of the famous swimsuit model - known best for her curves- is being featured black and white in a tangerine t-shirt designed by Marc Jacobs.

The legend "Protect The Skin You're In" covers Upton's "key assets."

"I love it," Upton tweeted on Tuesday referring to the t-shirts.

The t-shirts sell for 35 dollars each, according to Marc Jacobs' website. All proceeds from the sale will be donated to New York University's Skin Cancer Institute.
