Following her visit to the National Maritime Museum earlier today, Kate Middleton joined the Queen at Buckingham Palace for one of her famous garden parties.

The Duchess of Cambridge opted for a stunning, pale pink lace Alexander McQueen dress with a matching Jane Taylor hat for the occasion. This isn't the first time we've seen the regal look as she wore it to the 2012 Diamond Jubilee service at St. Paul's.

During the afternoon fête, Middleton mingled with guests amidst the 40-acre gardens and celebrated Prince Philip's 93rd birthday. See the arresting daytime look, below:
