@tatlermagazine: Few royals understand the power of fashion to connect quite like the #PrincessofWales. As London Fashion Week gets underway, the Duchess of Rothesay – as she is known in Scotland – championed one of Britain’s most iconic fashion houses during a joint engagement with Prince William on the Isle of Bute. Catherine stepped out in a dark brown #Burberry trench coat as she began her tour of the Scottish island, proving once again that her influence on international fashion – famously dubbed the ‘#KateMiddleton Effect’ and estimated to have contributed £1 billion to the British economy – is alive and well. Burberry is particularly timely, as the legendary British brand prepares to take centre stage at a V&A exhibition later this month celebrating the best of British style.
