Kate Middleton - Duchess of Cambridge
Words aren't necessary. the Dutchess is simply stunning.
The first occasion on which Kate wore (or in this case, held as an accessory) the scarf in public was soon after her wedding, at the Queen's Diamond Jubilee pageant on the Thames in 2012.
In the years since, the Duchess of Cambridge (or Countess of Strathearn) has worn her DC Dalgliesh scarf on countless occasions... and the Strathearn tartan has become quite iconic for her.
And the publicity has done us no harm! Here's an item about the Kate effect from ITV's flagship current affairs show, Tonight.
