Zoe Saldana poses in pink underwear in honor of Breast Cancer Awareness Month

'I wear pink in honor of all women I know and love who have battled breast cancer'

Zoe Saldana showed off her stunning figure on Monday for a good cause.

The 42-year-old actress took to Instagram to post an eye-catching beachside photo in which she's wearing a pink bra and bikini briefs. The star revealed she posted the photo in honor of Breast Cancer Awareness Month.

"I wear pink in honor of all women I know and love who have battled breast cancer. It’s breast cancer awareness month and I’m joining my friends @kitundergarments company for #kitstokickcancer!" she captioned the pic.

Saldana noted that the clothing company has partnered with the Women's Cancer Research Fund (WCRF) and 5% of sales will be donated for the entire month of October. Additionally, $1 will be donated to the WCRF "for everyone who posts a photo in their undergarments," she said.
