It's been a busy couple of days for our Kate - what with weddings, 90th birthday celebrations and royal engagements - but the new Duchess saved her most stylish look yet for yesterday.
Kate stepped out to support her husband and watch the procession of the Order of the Garter Service with Camilla Duchess of Cornwall in London - and was looking utterly chic in top-to-toe silver.
The young royal opted to wear the silk-satin Buxton dress and beaded lace trim Buxton coat, both by London-based designer Katherine Hooker.
The elegant dress coat was specially designed just for the Duchess, to feature an intricate antique clasp.
A striking silvery fascinator, matching box clutch and dove grey suede shoes completed the immaculate ensemble.
Looks like someone is really getting the hang of these royal engagements...
(Oh, and style points to Camilla for her complimenting shades of gold).
