Princess Kate went out with a bang at her final event in New York City on Tuesday evening.
With Prince William by her side, the expectant mother dazzled in a midnight blue dress by Jenny Packham (she also wore it to a 2013 event) and diamond and emerald earrings at St. Andrews’ 600th anniversary dinner at the Metropolitan Museum of Art.
The event, honoring the school where the two met and fell in love, was considered a highlight of the couple’s trip to the U.S. and the main reason the visit was scheduled for these days, according to the palace.
To great cheers from fans across the street and flashing lights of the press and TV cameras, Kate and William arrived, and at the top of the steps, they were welcomed by a group of St. Andrews alumni.
“It was wonderful to meet them and they asked if we were former students. It’s great to have them here,” Caroline Guenther, 27, told PEOPLE, adding that Kate “looked beautiful. This will be a great night.”
On the menu at the Met: Duo of mushroom-crusted tenderloin of Angus beef and cedar plank Scottish salmon with a Scotch ale reduction, truffle-whipped parsnips and potatoes and miniature sticky toffee pudding with caramel gelato and praline brittle.
Still, the glam evening (where Mary-Kate Olsen and Olivier Sarkozy, Anna Wintour and Seth Meyers were also in attendance) was one of just many exciting Stateside events for the royal couple. Among the highlights: A rendezvous with President Barack Obama and an encounter with America’s own “royal” couple, Jay Z and Beyoncé.
On Monday, William gave a speech at the World Bank in Washington, D.C., where he spoke out against illegal wildlife trafficking. Meanwhile, Kate charmed children in Harlem, who were so taken with her that they thought she was the princess from Frozen.
The pair, both 32, reunited on Monday night for a conservation reception at British consul general’s residence, followed by a basketball game at Barclays Center in Brooklyn, where they posed with LeBron James.
They will head home after Tuesday night’s dinner.
