Meghan Markle was a vision of white in a custom Louis Vuitton gown Tuesday night at the Ripple of Hope Awards in New York City.

The Duke and Duchess of Sussex both received the Ripple of Hope Award, presented by the Robert F. Kennedy Human Rights nonprofit organization. The couple was honored for the humanitarian work they do through their own Archewell Foundation, where they’ve focused on creating awareness around issues relating to racial justice, sexism, mental health, and more.

The Duchess look was designed by Nicolas Ghesquière. She accessorized with a Givenchy clutch and an aquamarine ring from Princess Diana’s personal collection, the same ring she wore on her wedding day.

During the evening Prince Harry joked that he and Meghan don’t get out much because they have small children and thought the evening was just “date night.”
