Always the fashionista, Kate arrived to the game in a navy blazer, white top and a blue and white polka-dot skirt. Her accessories stuck to the blue and white theme, with a simple pair of white pumps, white handbag and some jewelry.
Though the mom-of-three has been vaccinated, she wore a face mask during portions of the outing.
The Duchess of Cambridge got her first shot on May 29 at London’s Science Museum. "I’m hugely grateful to everyone who is playing a part in the rollout," she said at the time. "Thank you for everything you are doing."
Game on! The royal looked enthusiastic as she watched the match go down from her seats.
In May, Kate and husband Prince William played against each other in a game while visiting Scotland. The latter came out victorious.
Kate has revealed that 7-year-old son Prince George took up tennis a few years ago. In fact, he took lessons with champ Roger Federer!
"At that stage it's all about just touch the ball, it's already good," the professional said of the tot's skills.
The athlete was also asked about a report that stated he was George's favorite player.
"I think I have a little advantage that I actually spent some time, you know, with him," he responded. "I'm the only player he's ever met. Then you have a little head start in who is your favorite player."
At one point, the royal visited the Wimbledon Lawn Tennis Museum, which was opened by the Duke of Kent in 1977. She shared a peek inside via social media, showing off cases of trophies, memorabilia, photographs and more.
All in a day's work! Kate put her face mask back on before leaving the event and heading home.
