All of Kate Middleton’s best outfits from her Boston tour with Prince William

Kate Middleton and Prince William are back in the USA.

The Waleses touched down in Boston on November 30 for a three-day visit to Boston in celebration of the Earthshot Prize Awards on December 2, marking the royal couple’s first trip to the United States in eight years.

And the Princess of Wales, 40, pulled out all the sartorial stops for the occasion, showing out in a series of designer styles ranging from sharp suits to patterned dresses — and even a vintage treasure or two.

Below, get the scoop on each and every look Middleton wore in Boston.

Well suited

The princess arrived at Boston’s Logan International Airport dressed in a sleek, chic Alexander McQueen pantsuit paired with a matching turtleneck, accessorizing with Gianvito Rossi suede pumps and Princess Diana’s diamond-and-sapphire earrings.

Pretty in plaid

Later that day, she changed into a green tartan Burberry dress for a meeting with Boston Mayor Michelle Wu, perhaps in honor of St. Andrew’s Day in Scotland. On top, the royal kept warm in a bespoke green coat by her go-to designer, Alexander McQueen.

She finished her look with a matching green Mulberry handbag ($1,035) and Emmy London heels ($430), along with Shyla London pearl earrings ($89).

Courtside Chanel

The Princess of Wales closed out Day 1 of her visit by taking in a Celtics game — but rather than sporting, say, a basketball jersey to cheer on the team, she showed up wearing her royal blue vintage Chanel jacket.

Middleton teamed the piece with skinny black pants and black pumps along with chunky gold jewelry, debuting a new Laura Lombardi chain necklace ($158) and Shyla London hoop earrings ($90).

Business-y burgundy

For the second day of the royals’ trip, Middleton visited a climate tech lab and a youth charity, matching with Prince William — who sported a maroon sweater — in a burgundy pantsuit by Roland Mouret paired with a pale pink tie-neck blouse.

She added burgundy suede pumps and gold-and-diamond Daniella Draper hoop earrings ($3,100) for her busy day in Boston.

Brown on the town

The prince and princess joined Mayor Wu and Boston’s Chief of Environment, Energy, and Open Space, Reverend Mariama White-Hammond, for a walk around the waterfront on Thursday afternoon, with the mom of three wrapping up in another new custom coat from Alexander McQueen.

She paired the long chocolate-brown style with matching suede boots, a coordinating brown scarf and Cornelia James gloves ($173), wearing an orange turtleneck sweater ($790) and midi skirt ($1,590) by Gabriela Hearst underneath.

Houndstooth at Harvard

Friday morning started off with both royals paying solo visits in the city, with Middleton stopping by Harvard University in a blue houndstooth dress by Emilia Wickstead. She styled the prim collared piece with a coordinating Mulberry bag and textured gold Lenique Louis hoops ($340).

Green queen

The Princess of Wales pulled out all the stops for the culmination of the couple’s Boston trip, making a sustainable choice at the Earthshot Prize Awards by sporting a bright green Solace London dress ($525) borrowed from rental platform Hurr.

But the real star of the show was the emerald-and-diamond choker famously worn as a headband by Princess Diana, a piece that has been tucked away since the late royal last wore it decades ago.

While we didn’t see much in terms of American labels on this mini-tour, the Princess of Wales definitely flew the flag for high fashion.
