National No Bra Day is observed on October 13 each year. This day encourages women to go braless as a way to promote breast cancer awareness and support those affected by the disease. It aims to spark conversations about breast health and the importance of regular check-ups. The day also serves as a reminder for women to perform self-examinations and seek medical advice if they notice any changes in their breasts. By raising awareness, National No Bra Day contributes to the broader efforts of organizations like Breast Cancer Research Foundation and Susan G. Komen in the fight against breast cancer.
