The Duchess of Cambridge wore Alexander McQueen to find out more about her grandma's role in World War Two.
Kate Middleton has worn Alexander McQueen again for a solo visit to Bletchley Park in Buckinghamshire. We make that three Sarah Burton designs in the last week, not that we're counting, or jealous, you understand.
The Duchess of Cambridge was first seen wearing this particular Sarah Burton for Alexander McQueen dress when she and Prince William visited Birmingham in the aftermath of the 2011 riots.
Today's visit had a very different purpose though. The Duchess made the visit to Bletchley Park to see where her paternal grandmother, Valerie Glassborow, worked as a codebreaker in the Second World War.
It emerged today that the work of her grandma, and the other intelligence officers (spies, basically) helped shorten WW2 by between two and four years. Incredible.
During the visit, Kate chatted with Lady Marion Body, who worked with her grandma and her grandma's twin sister, Mary, and checked out the results of a year-long £8 million restoration of the site.
