The Duchess of Cambridge wore Alexander McQueen to the Queen's bash.
Kate Middleton, the Duchess of Cambridge, opted for Alexander McQueen for her surprise appearance at the Queen's garden party yesterday.
Kate wasn't expected to attend the bash, as she was due to go to a Red Cross Garden Party on Thursday with Prince Charles, but a last-minute change of plan meant Kate rocked up with the Queen.
You probably recognise the Sarah Burton-designed lace frock from the Queen's Diamond Jubilee Lunch back in 2012.
K-Midd had made a few slight adjustments to her look for the party, held at Buckingham Palace. She'd removed the nude waistband and styled it with a different Jane Taylor hat. Those faithful nude court shoes remained, though.
The garden party was thrown in honour of Prince Philip's 93rd birthday and it saw 8,000 guests descend on the grounds of the Palace.
Earlier in the day, the Duchess joined Olympic sailor Sir Ben Ainslie as he launched Britain's bid to win the America's Cup.
Kate met crew and boat designers during a breakfast reception at the National Maritime Museum in Greenwich.
