For a breakfast reception at the Royal Maritime Museum, the Duchess of Cambridge wore a fittingly nautical-inspired dress from luxe-high street label Jaeger.
The nation’s style icon is famously frugal and the Brits love her for it- her classic frock cost just €120.
Kate complimented the simple monochrome shift with a pair of Alexander McQueen midnight blue court shoes, a black clutch and understated jewellery.
This outing was her first solo engagement since the Royal Tour of Australia and New Zealand.
Olympic sailor Sir Ben Ainslie London was in attendance at the event as he launched Britain's bid to win the historic America's Cup yacht race.
In the shadow of the National Maritime Museum in Greenwich, south east London, Sir Ben told Kate about the plans to win the coveted trophy.
He will skipper the team that aims to triumph in the 35th America's Cup being staged in 2017, with the entry made through the Royal Yacht Squadron club.
The Royal Yacht Squadron club hosted the first race which took place off the Isle of Wight in the mid-19th century - but a British team has never won it.
The Olympic sailor said: "We want to bring it home, it would be an amazing thing for this country."
Kate is also a keen sailor and watched some of the London 2012 Olympic racing on the Isle of Wight.
