Kate Middleton's North American Tour Style

You knew she wasn’t going to wear sweatpants to cross multiple time zones on her (private) plane to Canada, but wow, she sure does look trim and flawless in this Smythe one-button blazer and navy sheath dress with a Mulberry tote.

K-Midd deplaned in Canada in a navy lace shift by (appropriately) Erdem Moralioglu, a Canadian designer based in London.

The Duchess is nothing if not a recessionista—she rewore the white Reiss dress she wore in her engagement picture to celebrate Canada Day.

On the second evening of her sartorial North American journey, KMid kept things classic and conservative while checking out the Canada Day concert's pop acts with hubby Wills.

The Duchess got down and dirty for a little tree planting ceremony in an elegant collared, grey sheath with cuffed sleeves, by the late Catherine Walker, and pointy-toed LK Bennett pumps.

Kate Middleton revisited native-Canuck designer Erdem for her arrival in Quebec. The dress, from the now England-based designer's pre-fall collection, stays true to Kate's form: a body-skimming knee-length shift in royal blue.

On the fifth day of their North American tour, the Duchess opted for a 1920s-style cream and navy cable knit dress with a pussy-bow neckline by Sarah Burton for Alexander McQueen.

Kate Middleton kicked off day six of The Royals In Canada in a beige linen shift with an olive grosgrain ribbon at the waist by danish designer Malene Birger. She complemented the dress with the nude LK Bennett platform pumps that we’ve seen earlier on this trip and a simple box clutch.

Always practical, she deplaned at Yellowknife in the navy one-button blazer by Canadian label Smythe that we saw her wear a few days ago when she started this trip. Plus J Brand skinny jeans she wore on Prince Edward Island yesterday, and her beloved espadrille wedges.

The D of C got into the Western spirit at the Calgary Stampede activities in Canada. Normally we shy away from a cowboy hat (unless it’s on Madonna in her “Don’t Tell Me to Stop" video, awesome), but we love her effort and it is a breath of fresh air to see her in such a different style.

Kate Middleton touched down at the Calgary International Airport in a daffodil yellow dress by British designer Jenny Packham.

Kate Middleton bid adieu to Canada in a stunning, bright red coat dress by Catherine Walker—a vibrant contrast from the subdued grey shift by the same designer, which she wore earlier in the trip.

Upon her arrival at LAX, Kate Middleton slipped out of her Catherine Walker coat dress and into a dove-grey, draped Roksanda Ilincic sheath dress, while opting to keep her tootsies in the same go-to LK Bennett nude pumps from before.

The Duchess donned American designer Diane von Furstenberg for the welcome reception at the British consulate-general's residence in Los Angeles.

Bring on the glamour! Kate Middleton gave us something to swoon about when she arrived on the red carpet for the 2011 BAFTA Brits to Watch Event in an ethereal, pale lilac, pleated gown by Sarah Burton for Alexander McQueen.

The recessionista wore a skirt and top by British high-street label Whistles for her last day in the US.
