Calendar Girls (2003)

"Calendar Girls" is based on the true story of a group of women who bare all for charity and become international celebrities as a result. The Women's Institute in Great Britain encourages the ancient skills of jam-making, flower pressing, knitting and baking. So when a group of extraordinary women are looking for a new way to raise money, they decide to take the annual 'Women's Institute Calendar', normally featuring landscapes or flowers, and create something traditional - but with a twist. Behind the baked goods, the apple pressing and the flower arranging, the women are completely nude.
