Kate Middleton Wore the Sweetest Shade of Yellow to the Royal Wedding — Down to Her Shoes

Update June 5, 2018: After much speculation, it turns out Kate's royal wedding guest look was not a repeat! Many people mistook her canary yellow Alexander McQueen design for the ivory ensemble she wore to Princess Charlotte's christening. Zoom in on the details that distinguish one look from the other here.

Original Post: If you associated gold jewels and sparkling silver diamonds with the royals, Kate Middleton's wedding guest outfit is a fresh, modern change. Making her first official appearance since giving birth to baby Louis, the duchess looked to a trusted designer: Alexander McQueen. (If you recall, she wore a Sarah Burton gown to her own wedding and chose a dusty rose dress from the fashion house for her sister Pippa's nuptials.)

Kate looked regal in the look, which is actually a repeat — she wore the same number to Princess Charlotte's christening in 2015 and again in 2017. This time around, Kate accessorized with Jimmy Choo pumps and a fabulous Philip Treacy hat. Nonetheless, her message was loud and clear: "Oh, this old thing? Nah, focus on the bride." Ahead, get an all-angles glimpse of her outfit, then see what the rest of the guests put on for the special occasion.
