The Duchess of Cambridge and dog Lupo join Prince William at the Polo

The Duchess of Cambridge and her black cocker spaniel Lupo joined Prince William and Harry at the Audi Polo Challenge in Ascot yesterday afternoon (May 13).

The 30-year-old future queen wore a £290 Libelula teal petal print frock teamed with a pair of towering wedges to the charity event which this year saw proceeds going to Prince Harry's charity Sentebale, supporting orphans and vulnerable children in Lesotho.

On Friday night, the Duchess wowed crowds and fellow guests in a teal Jenny Packham gown and pair of silver Jimmy Choos for the Our Greatest Team Rises gala dinner at the Royal Albert Hall to celebrate the countdown to the London Olympics 2012.
