Catherine, Duchess of Cambridge and Prince William took part in a morning prayer service today onboard a Canadian military frigate as they prepared for a day in Quebec City.

The Duchess wore her second Erdem look of the tour. Opting for yet another blue dress.

Her fitted 3/4 length sleeve Pre-Fall 2011 dress with a lace yoke and floral embroidery on the bodice was paired with her favourite L.K. Bennett nude pumps.
