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.

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

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.

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

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

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

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
