Last Thursday marked fifteen years since the death of Queen Elizabeth the Queen Mother, who was the wife of one British monarch and the mother of another. In honor of the anniversary of her passing, I’ve been digging into archival footage of her glittering gala appearances to bring you moving images of some of her gorgeous tiaras. Enjoy!
