Kate chose a Catherine Walker design for her going-away look today.

Charlotte waves goodbye to the staff.

More from Richard Palmer’s story for The Express:
A huge crowd turned out to bid the Duke and Duchess of Cambridge and their children farewell as they flew over the harbour and out to a military airport from where they were travelling home to Britain in a Royal Canadian Air Force Airbus A 310.
George was really a character. He started out waving with both arms.
But ultimately decided one would suffice.

Initially, she was a little nonplussed.
Kensington Palace released a statement from William thanking Canadians:
“Catherine and I are incredibly grateful to the people of Canada for the warmth and hospitality they have extended to our family over the last week.
We have loved our time in British Columbia and Yukon and will never forget the beautiful places we have seen and the many people who have been kind enough to come to welcome us in person.
Now to what the Duchess wore, beginning with her Catherine Walker coat.
The coat has a modified princess silhouette, an inserted waistband, off-center front closure, front flap pockets, and a hidden placket. The collar, pockets, and seams are all accentuated by trim in a slightly darker hue than the coat fabric.
Kate has a fondness for Catherine Walker pieces when on tour. From left to right: the ensemble worn when arriving in New Zealand in April of 2014; another red suit, this one worn when Kate and William were leaving Canada in July 2011; today’s coat.
You can just see a pleated dress or skirt peeking out from the coat.
Hannah asked a good question on Twitter: was the Duchess wearing the Whistles Lina Dobby Skirt we’ve seen previously?
It looks like she probably was, the skirt was first noted when the Duke and Duchess were in Los Angeles (above) during the 2011 North American tour.
We saw Kate’s Floret pumps in the ‘trench’ (nude) color from LK Bennett. The shoe is identical to Kate’s Fern heels of the same color, but the heel is shorter, 3.5″ to the Fern’s almost 4″. We show the shoe at LK Bennett, but it is also available at Nordstrom, as well as Shopbop.
Kate also wore her her Annoushka Pearl Drops and Kiki McDonough Diamond Hoops.
The Queen’s diamond and platinum Maple Leaf brooch made its final appearance of the tour.
Kate’s hair was partially pulled back.
Charlotte happily smiled and waved.
The Prince and Princess were on their best behavior.
Both looked darling.
Then it was time to leave.
And a final wave goodbye.
A lovely WKW friend was in Victoria watching their seaplane takeoff and shared this beautiful photo.

Don’t forget, you can get all of the details on what Charlotte and George were wearing over at What Kate’s Kids Wore. Next week we’ll see the first of our tour polls, as well as some things we missed along the way.

Its a well-tailored coat and the piping helps lift it from boring. But I am getting quite tired of all the high fastened collars, which has become Kate's go-to style. I also think the waist is slightly too high on the coat - deliberately placed to make her legs look longer? But it is another very conservative look, and in this case, too formal for the occasion. On the other hand, the hair worn down with the side pieces pulled down is too young a look for the formal and high collared coat. Hair should have been pulled back. But not the right look for this "event". I do think she is in a style rut, frankly.

I love following this blog--Kate's style is fascinating. Also, I love to knit, and have been looking at Charlotte's cardigans. She seems to have an array of those. I haven't had much success in finding knitting patterns for cardigans similar to Charlotte's. The burgundy cardigan she wore when leaving Canada looks rather simple. Can anyone suggest where I might find a pattern for toddler cardigans similar to Charlotte's?

Are you on Ravelry? I'm sure you could do a search or ask a question in the forums and come up with something!

I think Kate's wardrobe was stunning throughout this trip. She looked glamorous and very well put together. I was reminded of Grace Kelly. She must have employed a stylist to help her because the clothes she wore were not same ol' same ol'. Of course she has a personal style which she has been faithful to, but ramped way up. No flighty skirts that expose too much in a pesky wind, no wedge shoes (although they are, on all fairness, out of season). In fact she actually departed from her norm and wore different styled shoes! No unruly school-girl hair either - truly, her hair stylist did a superb job. Kate's hair was worn in a variety of flattering styles and looked very polished and appropriately styled at all the events. Her hair became a lovely accessory. All told, I think Kate looked very regal yet accessible at the same time. She hit this tour out of the park!

I agree, ygb. The clothes on this tour really looked like the wardrobe of a future queen.

Catherine and family looked very regal on arrival and departure. She is doing a wonderful job of balancing the vareous roles - regal when required and nature or athletic when required. Bravo on a fantastic fashion tour!
