When choosing an outfit for her brother-in-law Prince Harry's wedding to Meghan Markle, the Duchess of Cambridge opted for an ensemble from the very same designer she wore on her own wedding day: Alexander McQueen.
According to Kensington Palace, Kate wore a primrose yellow wool silk tailored coat by the British fashion house, whose creative director Sarah Burton was tasked with designing the now-iconic gown worn for the Duchess's 2011 wedding to Prince William. Her hat, in a matching pale yellow hue, was designed by Philip Treacy, while her shoes are by Jimmy Choo.
If Kate's ensemble looks familiar, that's because she's previously worn the outfit for two high profile occasions: the christening of Princess Charlotte, and the Queen's birthday party.
The Duchess's simple ensemble is remarkably similar to her outfit for her sister Pippa's wedding to James Middleton in 2017, which was another McQueen creation in a powder pink shade.
One of the last members of the royal family to arrive at Windsor, Kate arrived in a car with the page boys and bridesmaids (including, of course, her two eldest children Princess George and Princess Charlotte), along with the mothers of the young bridal party (including Meghan's close friend and unofficial maid of honour Jessica Mulroney). Once inside the chapel, the Duchess sat next to Camilla, Duchess of Cornwall, and Prince Andrew.
The wedding marks Kate's first public appearance since giving birth to her third child, Prince Louis of Cambridge, on April 23rd. The youngest member of the Cambridge family is not attending his Uncle's wedding, and is most likely being looked after by the family nanny, Maria Borrallo.
