In signature Kate style, she repurposed her entire outfit for the special occasion while incorporating a few sentimental pieces of jewelry into the look. Getty Dressed in a white Alexander McQueen blazer dress that she's worn once before, Kate paired the long suit jacket with a white and navy Philip Treacy hat and a few pieces from Princess Diana's jewelry collection that were a wedding gift from Prince William. Paying tribute to her late mother-in-law, the Duchess of Cambridge accessorized with a pair of double sapphire drop earrings, each surrounded by ten diamonds, and a matching necklace from the same set as her engagement ring. Diana, who had an affinity for sapphires, was initially gifted the jewels for her wedding from Crown Prince Fahd, and wore the entire set to a Brisbane state reception in 1983.

At the event, the Cambridge kids rode in a horse-drawn carriage alongside their mom, and twinned in varying shades of blue. Charlotte wore a cornflower blue dress with matching ribbons in her hair, while George looked all grown-up in a navy suit. Louis, meanwhile, rewore his father Prince William's baby blue mini sailor suit, which the Duke of Cambridge originally debuted at age 2 in 1985. Today kicked off a long weekend of festivities celebrating the Queen's Platinum Jubilee. In addition to the parade, there will be a service of Thanksgiving at St. Paul's Cathedral, the Derby at Epsom Downs, a live concert, and a Jubilee-themed lunch and pageant.
