Chelsea Handler's collaboration with Stella McCartney for Breast Cancer Awareness

Chelsea Handler has been known to strip down to her undies — and less — as a punchline on her TV shows and Instagram feed. Now, the comedian and TV host is bearing her body for a good cause. She’s the face of Stella McCartney’s campaign for Breast Cancer Awareness (October is Breast Cancer Awareness month), which breaks today on the designer’s web site and social media channels. For the third year, McCartney has designed a new Stella Lace bra and panty set as part of her fall lingerie collection, a portion of the proceeds of which will be donated to the Breast Cancer Research Foundation in the U.S. and the Linda McCartney Centre in Liverpool, U.K. Handler appears in the campaign in this year’s set, a pink bralette and bikini brief with striped elastic detailing and lace. Kate Moss and Cara Delevingne were previously posed in McCartney’s campaign.

“Breast cancer is the second most common cancer in women all over the world and does not discriminate,” said McCartney, whose mother Linda died of breast cancer in 1998. “While most people are aware of this terrible disease, many also do not take the steps to regularly get checked to detect it at its early stages. This set I designed is meant to serve as a reminder to women to consider their health and visit their doctor regularly. It not only looks and fits great, but is also an important healthy reminder.”

The bralette and brief are available for $35 to $70 at McCartney’s stores as well as Le Bon Marché, Saks Fifth Avenue, Myer and Net-a-porter.

McCartney also designed the Louise Listening post-double mastectomy compression bra, all proceeds of which will be donated to the Hello Beautiful Foundation, a London-based Cancer charity founded by Jane Hutchison.
