No Bra Day was initially observed on July 9, 2011, but within three years it had moved to October 13, the month of National Breast Cancer Awareness Month.
Some women embrace No Bra Day as a political statement while others prefer the comfort of discarding what they view as a restrictive, uncomfortable garment.
While some are marking it from the main point, the breast cancer awareness, others who feel it should be marked ‘romantically’ are turning the whole thing into something else.
Some have brought in comedy into the celebration.
