For generations Britain’s royal babies have worn a remarkable, unique hand-me-down: a Honiton lace and white satin gown that Queen Victoria commissioned in 1841 for her eldest daughter’s christening. The gown was worn by more than 30 blue-blooded babies, including Baby Cambridge’s forebears: Prince William, Prince Charles, Queen Elizabeth II, and the Queen’s father, King George VI until 2004, when it finally became too fragile for use. Now the original is safely tucked away in storage, and the newborn Prince George will wear a replica of the extraordinary heirloom upon his christening.
