Another day, another outfit change!

For Sunday's leg of her Canadian tour with husband Prince William, Kate Middleton dazzled in a cobalt blue lace detail "Jacquenta" dress by Canadian designer Erdem paired with four-inch nude platform stilettos. Finishing off the royal's weekend look? A mock-croc clutch bag and sapphire earrings.

All dolled up, Middleton, 29, joined her husband, also 29, bright and early Sunday morning for a prayer service aboard the HMCS Montreal, where the couple spent the night.

During the 45-minute interdenominational service, prayers were said for the newlywed royals and for members of the Armed Forces. The couple even sang along in French to the hymn "Je Louerai L'Eternel" (Praise, I Will Praise You Lord).

The prayer service wasn't William's only opportunity to practice his French. When the couple arrived at the Freedom of the City Ceremony, the Prince addressed his adoring public in their native language. "Thank you for your patience with my accent," he told attendees.

Later on Sunday, Middleton was seen visiting La Maison Dauphine, a drop-in center for homeless youth, in Quebec. Next up for the royal couple is a visit to Forts-de-Levis, a fort built between 1865-1872 under the supervision of British military engineers.
