Over 2,500 women broke the Guinness world record by skinny dipping in a sea at the Republic of Ireland.
Organisers of the "Strip and Dip" say that 2,505 women were adjudicated by a Guinness World Records official to have spent at least five minutes in the water at Magheramore beach.
Participants arrive on the beach.
The annual event, known as Strip and Dip, is in its sixth year after being launched by breast cancer survivor Deirdre Featherstone and this year was raising funds for Aoibheann's Pink Tie, Ireland's national children's cancer charity.
60 people attended the inaugural swim while numbers grew to 200 for last year's event.
"Oh my god it was wonderful". I have never been naked in front of anybody before, except my husband, and it was brilliant and bracing.
All money raised goes towards Aoibheann's Pink Tie, the national children's cancer charity which supports the families of children diagnosed with cancer. "We are all different shapes and sizes and ages and it was just super".
On Saturday, the sea temperature off Magheramore beach, where the Irish swim was held, was a bracing 12C, despite a recent spell of warm weather.
"This is a great women empowerment day", one participant told BBC. The charity was set up in 2010 by Mick Rochford and Jimmy Norman, after Jimmy's daughter, Aoibheann died from cancer when she was eight years old. We did it in her memory, ' said Betson.
