Go Topless Day is an annual event that promotes gender equality and body positivity by encouraging individuals to go without shirts in public spaces. It typically takes place on the last Sunday of July and aims to challenge societal norms regarding nudity and the sexualization of women's bodies. The event originated in the United States and has gained popularity in various cities. Participants often gather in parks or at beaches, advocating for the right to be topless in the same way that men can. Go Topless Day is also associated with the broader movement for women's rights and freedom of expression.
