Handout photo issued by the National Trust, showing some 400 people braving the cold waters and chill winds as they take part in a mass skinny dip, nude swim, in the sea at the Gower Peninsula in Wales, early morning, Sunday June 19, 2011. The mass event was organised by Britain's National Trust in an attempt to break the world record for the biggest ever skinny dip. The existing record is believed to stand at 250 naked bathers in one location and organisers of this event plan to submit their evidence to be considered as a new World Record.
