Kate wears an Eponine dress, sparkly heels

London: Kate Middleton and Prince William got all dressed up for the theater tonight, in support of their Royal Foundation.

The Duchess arrived wearing an Eponine dress and sparkly silver stilettos, believed to be Jimmy Choos. An equally glittery clutch and wavy blowout finished off the look.

The Duke and Duchess of Cambridge were attending a performance of Dear Evan Hansen, the hit musical centering on a teenager with severe anxiety. When Kensington Palace first announced that the couple would see the show, a tweet from the couple’s official account noted that the appearance was “in aid of The Royal Foundation.” The tweet added, “Mental health is a key priority for The Royal Foundation, which has developed initiatives such as [Shout] and [Heads Together].”

The Royal Foundation is Kate and Will’s charitable organization. (Prince Harry and Meghan also helped lead the foundation, before announcing this past year that they would split off and form their own.) Shout is a text helpline for those in crisis, and Heads Together is an organization that promotes awareness—and strives to combat any stigma—around mental health issues.

It’s been a busy month for the Cambridges, what with Kate traveling all over the UK to promote her early years survey, “5 Big Questions on the Under Fives,” and Will delivering a speech at the BAFTA Film Awards. But March is set to bring its own packed schedule of royal engagements for the couple—including, most notably, their first official visit to Ireland.
