Kate Middleton's Dress Paid Homage to Prince Louis in the Sweetest Way

On June 9, Kate Middleton joined the Duchess of Cornwall and the rest of the royal family — including the glowing newlyweds Prince Harry and Meghan Markle — for a fun day in London. The Duchess of Cambridge, who's been attending Trooping the Colour since 2011, once again stunned in a gorgeous baby blue dress by Alexander McQueen, which she accessorized with a hat by Juliette Botterill and Kiki McDonough jewels.

The celebration of the queen's official birthday marks Kate's first official appearance since Prince Harry and Meghan Markle's wedding — where she wore another stunning Alexander McQueen ensemble — and her second one since the birth of Prince Louis. As we patiently wait to see what she'll choose to wear for his upcoming christening, read on to get a closer look at her baby blue dress, which we can't help but think was a sweet homage to her third child.
