The Duchess of Cambridge is by now recognised to be the mistress of the wardrobe repetition. If it ain’t broke don’t fix it, and indeed the Whistles dress the Princess chose to wore for the closing ceremony when appearing next to Prince Harry was just as pretty as it was the first time around when she wore it to the Queen's Diamond Jubilee concert.

Trademark glossy waves and the addition of a slim black belt make the patriotic outfit princess picture-perfect.
