She wore it again that December, at a private fundraiser for the Royal Foundation of The Duke and Duchess of Cambridge and Prince Harry, (above right) and two years later, in November of 2018, she wore it again to the same private fundraiser (below right).

The dress, called 'Finella', came from a pre-fall 2016 collection by the British label Preen. It was described in the fashion press somewhat confusingly as being alternately 'modern, 'inspired by the Bloomsbury look of the 1930s', and 'evoking the mid-century style of the late Deborah, Duchess of Devonshire'. It retailed for about $1,700.
