Today, the Duchess of Sussex was in attendance at the U.S. Open to watch her friend, Serena Williams, go head-to-head against Canadian Bianca Andreescu.

The Duchess flew to New York at the end of this week, in what is believed to be a last minute addition to her schedule. The Duchess previously was seen privately supporting Serena Williams at Wimbledon this year, ahead of Archie’s christening in London. Today she was at Arthur Ashe Stadium in Queens (New York) for the Women’s Single Finals.

For this match she looked chic in a new J.Crew denim dress which she paired with her Carolina Herrera Matryoshka Locked L Tote, Victoria Beckham Sunglasses, and Jennifer Meyer earrings. Over her shoulder she draped a new knit jacket and around her neck a delicate necklace featuring 2 charms of “H” and “A” could be seen.
