The women pushed for equal rights, saying if men can take their shirts off in public, why can't women?
With strategically placed tape, women gathered with signs and megaphones protesting for equal rights.
"I think it's important to bring attention to the fact that there is gender inequality. Under the Arizona law, a man can go topless, but a woman can't and it makes no sense," said Ruth Carter, a protestor.
A handful of protestors gathered at Steele Indian School Park to show they're not afraid of baring it all.
Organizers say they hope being visible sends a message.
"The law has not passed yet for us to achieve our goal, to be able to go topless, so we're going to start rallying and petitioning until the law is passed in Arizona," said Beatrice Ngonmbi, an organizer.
"I think the message is to bring attention to the fact that it is just ridiculous that the law is different for men and women," said Carter.
Although there were some raised eyebrows from onlookers, protestors say this helps break down the stigma.
"I think we have to take a societal approach to changing the standards that we have for men and women and how we treat them," said Carter.
Go Topless Day always falls on the Sunday closest to Women's Equality Day, which is this Tuesday.
