Catherine, Princess of Wales, attended the Garter Day service at Windsor Castle today, alongside senior members of the Royal Family.
This year's event is the first under the reign of King Charles III, who will be taking part as the Sovereign of The Order of the Garter.
The Order of the Garter is the most senior and oldest British Order of Chivalry, founded by Edward III in 1348. Each year in June, a procession and service take place at St George's Chapel in Windsor Castle for the Order of the Garter. Prince William has been a Royal Knights Companion of the Garter since 2008.
The Princess debuted an Alessandra Rich dress for today's historic Order of the Garter service.
Rendered in a custom white and black polka-dot print, the £1,255 off-the-rack design was available in pink and blue (shown below). The fitted silk-satin midi dress features gathering details at the high-neck, shoulders, waist, and cuffs.
There are subtle differences between Kate's dress and the ready-to-wear version. Kate's dress replaces the gathered shoulder detail with a puff sleeve, and she opts for a standard buttoned cuff instead of a ruched cuff.
To complement the dress, Kate wore a new hat — a bespoke design by Philip Treacy. The chapeau features a black saucer base adorned with white and black polka-dot print feathers on top and underneath the brim.
The Princess also added new accessories. She carried a Strathberry 'Multrees' Chain Wallet in the Vanilla/Diamond colorway ($425). ID by Kate Middleton Style.
On her feet were a new pair of Jennifer Chamandi 'Vittorio' 105 slingback pumps in Ivory Leather & Black Patent toe cap ($715). ID by Emily Collins.
For today's outfit, the only familiar items Kate wore were jewelry pieces that had once belonged to her late mother-in-law, Princess Diana. She adorned herself with the Collingwood Pearl Drop Earrings, and the Nigel Milne triple-strand pearl bracelet.
And finally, a closer look at Kate's chignon.
