Kate Middleton dresses down for farm day in Gloucestershire

Kate Middleton swapped designer gowns in favor of a decidedly more casual look for a day in the mud on a local farm in Gloucestershire, England on Wednesday. The Duchess of Cambridge wore skinny jeans and boots as she jumped right in to work with children's author Michael Morpurgo and his wife Clare, who run the charity Farms For City Children.

The Duchess was shown around the farm by Michael and Clare, who set up the charity with the aim of giving city kids the chance to spend a week on a real working farm. During the engagement, Kate and the kids were also treated to a storytelling session by Michael, author of War Horse and Kensuke's Kingdom.

The engagement ended with a short tea party, where the Duchess met some of the charity's volunteers, trustees and staff.

Founded by Michael and Clare in 1976, Farms for City Children now has three working farms, where it welcomes around 3,200 children and 400 teachers a year. Children from all over Britain usually spend a week living and working on a real farm where they learn about where their food comes from, and develop practical skills outside the classroom. The charity's mission is to promote literacy and storytelling, as well as to give children an understanding of the countryside and food production.
