Princess Letizia is something of a fashion plate herself, so was there really any doubt that she would pass on her sense of style to her daughters?
The girls, Infanta Leonor, six and Infanta Sofia, five, looked super cute in their navy uniforms and matching blonde side braids on Friday as their parents, Prince Felipe & Letizia, led them to their classes at Santa Maria de los Rosales school in Madrid. Their little backpacks! The boots! (The pair have also been known to sport cute soccer jerseys.) Leonor and Sofia are second and third in line to the throne, after their father.
These too-cute pics remind us of Prince Christian of Denmark, who also sported an adorable backpack on his first day of kindergarten.
See pics of the girls' big day below, and for kicks, we dug up this YouTube of the girls as infants being, well, the cutest.
