Prince Willam and Kate Middleton kicked off their official tour of Canada and California yesterday, which means one thing peeps; we are on royal frock-watch! With an estimated 40 different outfits needed for the trip, Kate will be delivering our daily dose of fashion for the next 11 days. Whilst we've already picked out her our dream travel wardrobe, we're sure that whatever the Duchess chooses to wear will cause a retail stampede on said wrap dress/skirt suit/handbag. Speaking of, Catherine opted for a Brit/Canadian mash up on departure from London, wearing a very Brit Roland Mouret dress and Mulberry Polly Push Lock bag, which she teamed with a blazer from Canadian label Smythe. She changed mid-flight into something a little more femme, donning a lace frock by Canadian born designer Erdem, with nude heels, and the same clutch we saw her carry at Wimbledon for her arrival in Ottawa, Canada. Which travelling ensemble do you prefer on the Duchess? Her classic, tailored take-off two-piece? Or her lacy touch-down dress?
