A model has bravely walked through New York City with her breasts on display as part of a campaign for gender equality, leaving passers-by in shock.

Emily Bloom, 23, took part in the daring stunt to support Free The Nipple - a movement that campaigns for women and men to be afforded the same freedoms and protection.

She was filmed as she traversed the city by Norwegian photographer Petter Hegre, who specialises in female nudes.

The footage, which has had more than 400,000 views has recently resurfaced online after Petter uploaded it last year.

In the cheekily titled 'NYC Nude City Guide' some passers-by were hilariously oblivious to the display unfolding in front of them.

But those who did notice couldn't believe their eyes as Emily strutted past, and dissolved into fits of giggles while snapping her on their phones.

One New York City cop looked especially bemused, laughing and shaking his head as she strolled by.

The brave volunteer went for a carriage ride, shopped for second hand books, stopped off for a slice of pizza and a coke and even went for a jog with her top pulled up to reveal her bare breasts.

She also made a visit to Apple headquarters and Times Square and sunned herself on a fire escape.

The project has echoes of the 2014 Free The Nipple film where a group of women take to the streets of New York to protest against the taboos surrounding female breasts.

Campaigners argue they risk being arrested for disorderly conduct, whereas a man is unlikely to receive the same treatment for going without a shirt.

In most states in the US, there is no explicit law against going topless in public.

However, in May this year three Free The Nipple supporters were arrested for public nudity in New Hampshire.

Celebrities who have supported the campaign on social media include Cara Delevingne, Miley Cyrus and Rumer Willis.

Events have taken place across in the world including a topless protest on Brighton Beach in June.

Two hundred men paraded topless to highlight controversial social media policies about banning female nipples.
