The young royal, 10, joined Sweden's royal family in celebrating her grandfather King Carl XVI Gustaf's 76th birthday at the Royal Palace on Saturday. Alongside her parents, Princess Victoria and Prince Daniel, as well as her brother, Prince Oscar, Estelle appeared at a balcony window to wave to the crowds — and she sported a new accessory. For the first time in public, Princess Estelle wore a pair of black frame glasses for the outing. The rounded specs look a lot like the ones that have been worn by her dad, Prince Daniel, for many years. The first glimpse at Princess Estelle's new look came in March in photos released to mark World Water Day.
