Every October 13 is the annual No Bra Day, a day which has been set aside for women to go braless but originally that is not the case.
National No Bra Day is meant to promote breast cancer awareness and to help raise money for research. Many women who have survived breast cancer are unable to go without a bra as they need it to hold their prosthesis after surgery.
October is Breast Cancer Awareness Month and National No Bra Day should serve as a reminder for all women to be screened for breast cancer.
Here are pictures of how the day was marked globally with some ladies going nude.
