The King and Queen of Spain visited Buen Retiro Park today for the launch the 76th Madrid Book Fair.
The annual event aims to promote books, reading and organizations involved in the publishing, distribution or retail of books.
Their Majesties were joined by the President of Portugal at the fair which this year highlights Portuguese influence on literature.
The trio took a tour of the stalls and chatted with booksellers and publishers.
They also dropped into the Children's Pavilion for storybook time.
Despite the hot weather, Letizia managed to look cool in a crepe set featuring a pair of relaxed-fitting cream trousers and matching vest.
The top is fashioned with interlacing tank straps and a peplum waist.
ID UPDATE (29 May 2017): The set is by Sita Murt. This is the first occasion we have seen the Spanish queen step out in a design from the Catalan fashion house. Below we show a stock photo of the top.
Queen Letizia added a pop of colour with burgundy accessories. She carried her Felipe Varela suede clutch and on her feet she wore a matching pair of ankle strap pumps by LODI. We believe these are the shoes she first wore with her Felipe Varela gown at this year's Diplomatic Corps reception.
Letizia topped off the outfit with her interchangeable earrings from Spanish jeweler Coolook. She wore the smoky quartz 'Big Candy' stud earrings with the 'Hera' pendants.
