The Duchess was in town to view the special D-Day exhibition in the newly restored Teleprinter Building, marking the 75th anniversary of the D-Day landings. According to fashion experts Kate was 're-wearing' a polka dot Alessandra Rich midi dress with button detailing and a white collar.

She previously wore the frock in family photos released in honour of Prince Charles's 70th birthday.

She paired the piece with a clutch and powder blue pumps.

A tweet from Bletchley Park said: "We are delighted to welcome HRH The Duchess of Cambridge to Bletchley Park today to view our new D-Day: Interception, Intelligence, Invasion exhibition. "During her visit she will meet four Bletchley Park Veterans and Year 6 students from Akeley Wood."
