Catherine, Duchess of Cambridge and Princess Charlotte have once again proven they're like two peas in a pod with their latest appearances.
Stepping out for her visit to the 1851 Trust and the Great Britain Sail Grand Prix, the duchess was certainly dressed for the occasion with her very nautical choice of outfit.
The royal donned an Erdem cashmere navy jumper with white stripes, coupled with Holland Cooper tailored white shorts and Superga white joggers.
During her visit, the duchess took part in activities promoting sustainability.
She even changed into a wetsuit for a friendly race alongside Britain's team.
Meanwhile, her husband Prince William and daughter Princess Charlotte were busy with another sport - the UEFA Womens Euro Final.
The father and daughter melted plenty of hearts when they shared a video message in support of the England team, the Lionesses, ahead of the match.
"We both want to wish the Lionesses the best of luck for tonight," the duke said. "You've done amazingly well in the competition and we're rooting for you all the way."
Charlotte then added: "Good luck, I hope you win. Bye!"
And it looks like her hopes came true as the Lionesses took out the win against Germany with a final score of two to one.

In a special touch, Charlotte was donning a Losan Kids navy cotton t-shirt with white dots - which bore a sweet resemble to Catherine's own nautical outfit, as well as matching her dad's blue blouse.
Royal observers were also taken with just how much the young royal already resembles her mum.
"Gosh Charlotte is so much like her mother, especially that smile she gives before speaking," one user mused.
Following the Lionesses' triumphant win, Prince William was overjoyed to present the official trophy to captain Leah Williamson, as well as embrace midfielder Jill Scott with a warm hug.
The duke also took to Instagram to pen a celebratory message following the victory.
"Sensational. An incredible win @lionesses and the whole nation couldn't be prouder of you all. Wonderful to see history in the making tonight at Wembley, congratulations! W"
