Having stripped down for Calvin Klein underwear earlier this year for a 'Promise for Body' campaign, actress Choi Yeo Jin has done it again with the same brand for a 'Breast Cancer Awareness' campaign this time. In the photoshoot taken for W Korea recently which will be published in the November edition, Choi Ye Jin showed off her fine body again in her bra and panties. She said, "I am happy to be shooting this to promote the awareness of early detection of breast cancer. I hope that through this photoshoot, more women can start to take notice of their bodies and take precautions."
