Kate wore coat dress by her late mother-in-law Princess Diana's favorite designer Catherine Walker, a chic hat and Gianvito Rossi heels.

Kate and the Queen had attended one other engagement, although not a public one, in 2011 when they viewed the Duchess' Sarah Burton for Alexander McQueen wedding dress on display at Buckingham Palace.

Last year, it was Meghan Markle who had her chance to step out alone with Queen Elizabeth. The Duchess of Sussex was the first of the two granddaughters-in-law to enjoy the special privilege, accompanying the Queen on a visit to Cheshire, England, just a month after former Suits star Meghan married Prince Harry.
