Duchess of Cambridge at Royal Wedding 2018

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 light shade down to her toes, accessorising with Jimmy Choo pumps and a fabulous Philip Treacy hat. Ahead, get an all-angles glimpse of her outfit, then see what the rest of the guests put on for the special occasion.
