Kate Middleton, 38, has sent a message to the British sailing team in a video shared online. She wore a navy and white striped top underneath a British sailing jacket.
She also spoke of the experiences she and her husband Prince William have had with the competition.
“Six years ago, William and I raced against each other on the America’s Cup race boats during our visit to New Zealand which was hugely exciting.”
Kate will often show off her thrifty sense of style by recycling pieces from her wardrobe.
Tonight seemed to be no different as she was seen wearing a white and navy striped top.
The top design could only be seen partly but it appeared to be the ME+EM Breton top which she first wore in 2014.
The item has a casual fit with a slightly scooped neck and three quarter length sleeves.
The affordable piece was originally on sale for just £48, although it has now sold out.
During her video, Kate opted to cover up most of the design by wearing a sporting jacket.
The caption read: “Good luck message from Her Royal Highness The Duchess of Cambridge.
“Over 11,000 miles from home and about to take on the challenge of a lifetime, it’s inspiring to receive a message of support from The Duchess of Cambridge, Royal Patron of our Official Charity @1851trust, as we head into our first race day on BRITANNIA.
“Royal support for Britain’s challenge to the win the Auld Mug first dates back to the original race in 1851, when Queen Victoria saw America in first place and asked who was second, the reply came; ‘Your Majesty, there is no second.’
“That phrase, just four words, is still the best description of the America’s Cup and how it represents the singular pursuit of excellence.”
