But there’s something else at play, too. In March, the American artist Denise Jolly took to the pavements of Brooklyn in the buff. Jolly, who describes herself as ‘six foot tall, and 300lbs’, posed for photographs hailing a cab. The resulting pictures were celebrated as a triumph of body positivity. Perhaps this body-positive message explains why nudity isn’t just being embraced by the stars of the catwalk, red carpet and Twittersphere, but by ordinary Londoners, too. The organisation Spirited Bodies runs workshops at which women (and sometimes men — there is a mix of single-sex and mixed-gender events) can pose nude for artists’ groups. It was founded four years ago by professional life model Esther Bunting. Whereas, when she began, she struggled to find ten women to fill a workshop, each one now attracts a crowd of 20; demand for places outstrips supply. Held on an ad-hoc basis every few months, this year’s events have occurred at venues as diverse as the Royal Festival Hall and The Plough & Harrow pub in Leytonstone. ‘It attracts a real cross-section of ages and professions,’ says Bunting, 39. ‘Some have done it before, some are there for the first time. People come to feel better in themselves, to celebrate their bodies.’
