Kate visited Bletchey Park to view a special exhibition marking the 75th anniversary of the D-Day landings. She met other women there who, like her own relatives, were part of the effort to feed information to Allied forces before D-Day, the day in 1944 when Allied troops landed in Normandy, France.

Kate stood out at the exhibit Tuesday in a long-sleeve, flowing polka dot dress with white cuffs, white buttons and a white collar. According to royal fashion watchers, the navy dress was designed by Alessandra Rich.

The Duchess of Cambridge was seen in the same dress last November, when she and her husband, Prince William, posed in a family portrait with their three kids, as well as Prince Harry, Meghan, Prince Charles and Camilla to mark Prince Charles’s 70th birthday.

Kate, 37, is well-known for re-wearing and re-fashioning clothes for her many public appearances. When she stepped out for a gala in March, for example, Kate rewore a black floral Alexander McQueen gown to which she added capped sleeves, creating a new look.

After viewing the D-Day exhibit, Kate joined Prince William in making a special trip to Windsor to meet their new nephew, Archie Harrison Mountbatten-Windsor. William and Kate met the son of William's brother, Prince Harry, and his wife, Meghan, the Duchess of Sussex, at the family's Frogmore Cottage home.
