The Duchess and her husband Prince William watched Roger Federer scoop his eighth Wimbledon title, but it was Kate's new bouncy curls, and her attractive floral Catherine Walker summer dress, that had fans talking.
For the Men's Singles Final yesterday, which saw Roger Federer win an historic eighth title, the Middleton sisters both donned floral sundresses. She matched her floral frock with the same white Victoria Beckham tote she carried for her first visit to Wimbledon two weeks ago and accessorised her look with a Wimbledon-themed purple and green brooch, and gold earrings by Cassandra Goad.
Much like Kate, Lucy was also seen sporting a white dress, which flattered her tiny frame.
The Middleton sisters win big at Wimbledon
Classy and chic is always a good style to sport during the annual tennis tournament, and the Duchess of Cambridge did just that with great panache.
Kate looked phenomenal as ever as she cheered out for the players in delight.
After the match, the royals took a moment to congratulate Federer - a family friend of the Middletons, who attended Pippa's wedding to James Matthews earlier this year - on his victory.
The 35-year-old's sister Pippa Matthews and parents Carole and Michael were also in the audience, though evidently didn't score an invitation to the prestigious Royal Box - unlike Bradley Cooper, Eddie Redmayne, Hugh Grant and Teresa May.
