Scores of women bare their breasts to celebrate Go Topless Day.

In New York City two women are seen baring all while celebrating Go Topless Day Manhattan where, like many other states in the U.S. is is legal to do.

Scores of women around the world publicly bared their breasts Sunday as some vibrantly shook their chests, exclaiming: "The bells of liberty, let them ring!"

So was the scene at an estimated 30 cities from as far south as Caragena in Colombia to New York City, where both women and men celebrated Go Topless Day's fourth anniversary.

"If it's hot out and guys can take off their shirts, why not women?" said bare-chested Dylan Hall, 20, who was celebrating her second year's participation at Bryant Park. "We're all skin and bones, what's the difference between how much fat we have on our chests? We're all the same."

Alongside her were fellow veterans of the cause.

"The first time I did it was in Washington Heights and everyone was hanging out their windows looking at me," said Holly Van Voast, 48, of her first time in 2011.
