The 32-year-old toured Bletchley Park Wednesday, where her grandmother worked during World War II.
The Duchess of Cambridge wore a blouse and skirt from Alexander McQueen's 2011 Pre-Fall collection. Middleton first sported the military-inspired look during a Birmingham engagement in August 2011. She accessorized her ensemble by wearing Princess Diana's now iconic sapphire and diamond drop earrings.
Upon her arrival, Middleton met Lady Marion Body, who worked with her late paternal grandmother Valerie Glassborow during the war. Glassborow was a civilian member of staff and worked in Hut 16.
Her grandmother's workspace, now named Hut 6, was part of a restoration project at the "spy school."
During her visit, Middleton met with the restoration staff. She also pretended to decipher a Morse code message using a replica radio, similar to the ones that were used during the war. Later on, Middleton planted a tree to commemorate her visit and to celebrate the completed $13.6 million renovations.
