The Duchess of Cambridge and the Duchess of Sussex attended the Wimbledon women's singles final together on Saturday afternoon.
Both watched the clash between American star Serena Williams and Romanian pro Simona Halep on Centre Court from the Royal Box where they were joined by Kate's sister Pippa Matthews.
Williams was beaten 6-2 6-2 by Halep who is now the first Romanian to win a singles title at Wimbledon.
Kate, who who is patron of the All England Lawn Tennis Club (AELTC), was snapped ahead of the 2pm match meeting with the owner of Hugh Lowe Farms, the official strawberry supplier to the tournament, as well as young female tennis players.
For the occasion she opted to recycle a green Dolce & Gabanna dress which she previously wore in Canada in 2016.
Meghan, meanwhile, wore a crisp white shirt teamed with a floaty blue and white pleated skirt which was reminiscent of the outfit she wore for her first visit to Wimbledon last year - a crisp blue and white striped shirt and cream slacks.
It's the second time the sisters-in-law have appeared in public together this week having attended a polo match on Wednesday.
Meghan is close friends with Williams and turned up to support her during her match earlier this week.
That visit caused a stir as royal protection officers instructed fans not to take pictures of her as she was attending the match "in a private capacity".
Hasan Hasanov - one of the punters spoken to - said: "I had no idea she was there!"
The 58-year-old told the Sun: "I honestly couldn't really care less about taking a picture of Meghan, Harry or any of the royals - and, if I did, I'd ask first."
The Times also reported that Meghan was not supposed to be wearing jeans in the members' area of the club.
At the All England Club spectators are not required to stick to a dress code. However, those invited into the Royal Box are expected to wear a dress or jacket and tie.
Also watching the action from the Royal Box were Irish actor and Poldark star Aidan Turner while Wolf Hall actor Sir Mark Rylance and Doctor Who's Jodie Whittaker were also invited.
Meghan, who is on maternity leave following the birth of son Archie, will make her first red carpet appearance as a duchess when she attends the screening with the Duke of Sussex in London's Leicester Square on Sunday.
