The Princess of Wales's wardrobe is packed full of elegant options for formal occasions so we know when she picks a particular piece that a lot of thought has gone into her look. At this year's Trooping the Colour, the future Queen stepped out in a pale blue Catherine Walker coat dress with white piping along the crisp collar, pockets and cuffs.
Her sculptural hat matched the two tones of her frock perfectly and the rest of her accessories were plain white for a timeless feel. Prince William wore his scarlet Welsh Guards dress uniform for the occasion like we expected, but Kate's Trooping the Colour outfit subtly honoured her husband in a surprising way, as well as more obviously reminding us of Princess Diana.
