The movement started in 2011 and largely takes place on social media, where women use the hashtag #nobraday to campaign.
The aim is to raise awareness and encourage women to carry out self-examinations, screenings, and make sure they know the signs of breast cancer.
Men, and women who don’t want to go braless, are also encouraged to take part – by wearing something purple for the day.
While ladies are encouraged to get a mammogram screening on October 13 – which can help detect breast cancer up to two years before it can be felt by the patient or a doctor.
