A nude clutch and matching court shoes completed the look. Her signature straight locks had been tucked behind her ears.
Letizia proudly watched her husband officially accede the throne with the couple's two daughters Princess Sofia and Princess Leonor, who looked adorable matching pleated brocade dresses in different shades of blush and duck egg blue.
Felipe VI was officially proclaimed King of Spain on the stroke of midnight on Wednesday, following the abdication of his father, King Juan Carlos.

The new chapter in Spanish history was formally marked with a low-key ceremony at the Palace of Zarazuela, located on the outskirts of Madrid, at 9.30 local time.
Despite the importance and formality of the ceremony, it remained a touching family affair.
The king's first act was to officially receive the royal sash from his father. The two men then touchingly embraced as their family applauded. Felipe, dressed in his blue military uniform, then walked over to his loved ones, including his mother Queen Sofia, and kissed them all, while Juan Carlos shook hands with officials.
