About National No Bra Day
It might seem controversial at first, but this day is intended to raise awareness and reduce stigma about an important subject.
No Bra Day is an annual observance on October 13th on which women are encouraged to go braless as a means to encourage breast cancer awareness.
No Bra Day was initially observed on July 9th 2011, but within three years it had moved to the 13th day of the National Breast Cancer Awareness Month, October.
