The Spanish princesses commenced the school year today and were accompanied by their parents King Felipe and Queen Letizia on their way to the Santa Maria de los Rosales college.
Her Majesty chose a low-key outfit for the school run.
She teamed a khaki cargo jacket by Adolfo Dominguez with a white scoop neck tee and slim jeans.
Letizia also opted for a pair of comfortable trainers, wearing her light grey Hugo Boss 'Low Cut S' suede sneakers (US$295).
She complemented her youthful and casual style with minimal make-up and no jewelry.
