The King and Queen of Spain attended the prestigious 'Miguel de Cervantes' Award ceremony on Tuesday.
The annual event is held at the University of Alcalá in the town of Alcalá de Henares - the birthplace of Spain's greatest writer, Miguel de Cervantes who is best known for his masterpiece, Don Quixote.
The award is one of the richest literary prizes in the world and is the most regarded literary awards in Spain and Latin America. It honours the lifetime achievement of an eminent writer in the Spanish language. This year, Their Majesties presented the Cervantes 2018 Prize to Uruguayan writer, Ida Vitale.
Queen Letizia looked elegant in her grey Carolina Herrera double-face ensemble for the esteemed event.
The coat and matching dress is from the designer's CH Carolina Herrera line and belongs to the Fall 2016 range.
This is the fifth occasion Her Majesty has worn the separates since their debut in November 2016 during the State Visit to Portugal.
Today's decision to opt for a sartorial repeat is consistent with previous attendances of the 'Miguel de Cervantes' Award ceremony. However, this year Queen Letizia did not wear a set by Felipe Varela as she did in the past.
She again paired the Carolina Herrera co-ordinating separates with snakeskin accessories. Today Letizia chose the custom Magrit studded snakeskin pumps and matching clutch bag, which she debuted in February 2018 at the National Sports Awards.
She finished the look with her dazzling diamond cascading earrings, first seen at the 2014 Prince of Asturias Awards.
