Kate Middleton makes one smokin' spy! The Duchess of Cambridge paid a visit to the UK's Bletchley Park on Wednesday, June 18, stopping by the World War II code-breaking site. 

The brunette beauty, 32, looked gorgeous in an Alexander McQueen military-inspired number for the event. She wore a blouse tucked into a navy skirt with front slits, both from the designer's 2011 pre-fall collection. 

Middleton's cream-colored blouse featured navy trim and gold buttons, which were echoed on the front of the high-waisted pencil skirt. The royal wore the outfit once before, to an engagement in Birmingham in 2011.  

The fashion plate accessorized her look with a pair of navy pumps and a clutch purse to match. She kept her jewelry simple, sporting just a pair of silver earrings and her eye-catching sapphire engagement ring.

While at the historic site, Middleton tried her hand at some code-breaking, working on a World War II-type of device. She was pictured at Bletchley Park's Hut 6 building, where her paternal grandmother worked during the war. 

Middleton's visit coincides with a £8 million restoration of the park.
