Olivia Munn‘s putting breast cancer at the forefront of her new marketing campaign … modeling shapewear for SKIMS — and, revealing her surgery scars in the process.

The actress is the focus of Kim Kardashian brand’s newest campaign during Breast Cancer Awareness Month … posing in several different ensembles — and, speaking about some of her experiences fighting cancer over the last couple years.

The pics from the shoot show a lot of Munn’s body … including the surgery scar on her bare breast from her double mastectomy surgery last year.

OM dove deeper into the topic on “TODAY” this morning … saying they originally planned for the star to cover all her scars with makeup and the clothing — but, she says they had a tough time covering up the scars.

Olivia says she went to the top brass at SKIMS to talk about showing the scars … a vision they all agreed to.

Munn adds she was tired of hiding her scars from the world … and, she hopes to give women with scars like hers a sense of beauty even in the face of the disease.

It was earlier this year when Munn announced she had breast cancer … sharing an emotional Instagram post detailing all the procedures she’s gone through. She’s since talked more in-depth about her fight with cancer in follow-up interviews.

As well, 10% of retail sales of SKIMS bras sold between now and October 31 will go to the Susan G. Komen Foundation — a breast cancer nonprofit.
