Three women have taken their battle to bare all to the United States Supreme Court.

The trio who were arrested for topless sunbathing in New Hampshire want the highest court to intervene.

The plantiffs are part of the 'Free the Nipple' movement that seeks to empower women and stop sexualizing women's breasts.

It's been a legal fight for Ginger Pierro, Heidi Lilley, and Kia Sinclair, 27, since May 2016 when they were arrested for violating a Laconia city ordinance banning public nudity, including 'the showing of the female breast with less than a fully opaque covering any part of the nipple'.

'This movement is about equality and normalizing the female body as more than a sex object,' Sinclair tells the Daily Mail.

It started when Pierro was doing her yoga exercises topless at a lakeside beach. Three days later Lilley and Sinclair were arrested at the same beach, after taking off the tops in protest.

Laconia, which has a population of approximately 16,000, adopted the public nudity ordinance in concert with the annual Motorcycle Week. The New Hampshire Union Leader reports it was done to stem harassment of women. It prohibits any encouraging or harassing women to removing their tops or displaying their breasts.

'It is discrimination plain and simple.' Sinclair tells the Daily Mail. 'Women should not be arrested and/or fined for same behaviors men would not be punished for.'

Beyond any double standard, attorney Dan Hynes who represents the ladies says there is no state law forbidding toplessness.

Hynes, though, is not admitted to the Supreme Court. He tells the Union Leader he'll work on the brief and collegaue Eric Issacson, who will deliver oral arguments if it gets heard by the justices.

The Supreme Court is back in session on October 7.

If the case is not accepted, Hynes said, other options remain, including an appeal in U.S. District Court or lobbying for legislation to address the issue.

In February, the New Hampshire Supreme Court upheld the women's convictions in a 3-2 decision, clearing the way for the latest hurdle, the U.S. Supreme Court.

There is a legal precedent as also in February, the federal appeals court for the 10th Circuit struck down a topless ban in Fort Collins, near Denver.

The ruling found no justification for treating men and women differently when they wish to bare their chests, NBC News said.

'If they refuse to take the case, I'm not sure what our next step will be,' Sinclair tells the Daily Mail.

Sinclair says she's always been in a #MeToo world, 'so, yes, this change is needed.'
