The UK's 2012 Cheltenham Festival is in full swing, and Wednesday, which was Ladies Day, saw some pretty interesting hats, including those worn by Zara Phillips and Camilla, Duchess of Cornwall.

The horse racing event takes place annually in Gloucestershire, England.

Ladies Day has been around for six years now, and the website for the race encourages women to dress fashionably. There are even Fashion Awards for those who enter a prize contest.
