Hundreds of people – men and women – have come together for a peaceful, topless walk to "protest the double standard of nipple censorship, body shame and unwanted sexualisation".
The protest in Brighton is one of many worldwide events over the years aimed at empowering women to challenge the social norm that men can walk around topless in public, but women can't do the same.
Though the official Free The Nipple day to protest this inequality is in March, #freethenipple campaigns and events take place at any time and in any form.
Here's everything you need to know about the #freethenipple protest, including whether it's actually illegal for women to show their nipples in public.
What is Free The Nipple?
Free The Nipple is a global campaign group that aims to encourage equality, empowerment and freedom of all humans.
Inspired by a 2012 film of the same name, following Lina Esco and a group of women attempting to shed light on the societal norms that accepts topless men in public but shames women for the same, the organisation's mission is for all adults to be treated as equals.
The organisation also works to raise awareness and calls for change on a number of social issues and injustices.
The official website for the campaign reads: "We are a global movement of equality, empowerment and freedom. We are a movement of change."
Many celebrities, including Miley Cyrus, Kendall Jenner, Cara Delevingne, Rita Ora and Alanis Morissette, are advocates of the #freethenipple movement, either speaking out or baring it all out in support of the campaign.
Is it illegal to go topless in public?
In the UK, it is not illegal to strip off and go topless in open spaces.
Despite it not being illegal, there are heavy restrictions placed on going topless under the Public Order Act of 1986 and the Justice of the Peace Act from 1361.
It's considered a common law offence and thought to be indecent exposure, which prevents people from exposing themselves to other members of the public.
However, Brits are allowed to get naked at official events like bare bike rides and while sunbathing at nudist beaches.
