Queen Letizia was holding onto summer with her most recent outfit choice as she opted for a vibrant floral blue skirt for her public appearance in Madrid on Wednesday (7 September).

The Spanish monarch, 43, oozed elegance as she accompanied her husband, King Felipe VI, at the centenary of novelist and Nobel Laureate Camilo Jose Cela's birth commemoration at the Instituto Cervantes.

Always reigning in terms of style, Letizia created a fine balance between summer and autumn with her perfect in-between-seasons ensemble.

Returning to Madrid for her first royal engagement of the new season, the mother-of-two kept it chic and fashion-forward in a familiar outfit which we've seen her wear on more than one occasion in the past.

Proving that you don't have to wear a completely different outfit every time you attend a special event, Letizia wore the exact same, timelessly feminine outfit for the fourth time in recent years.

Comprising of a powder blue and floral adorned A-line skirt by Carolina Herrera paired with a royal blue blouse by her go-to Spanish fashion designer, Felipe Varela, Letizia completed the eye-catching outfit with navy suede strap sandals and a navy flap clutch, also by Varela.

She gave the outfit an extra twist with blue gemstone drop earrings while keeping her make-up fresh and natural with a rosy glow.

King Felipe looked his usual dapper self in a pinstripe navy suit worn with a sky blue crisp shirt and burgundy tie as he held his wife's hand at the event. Felipe has been married to his former news anchor journalist since 2004, and the couple wed in an idyllic cathedral in Madrid. They have two daughters together, Leonor, Princess of Asturias, and Infanta Sofia.

At the event, the couple were in high spirits as they chatted with Camilio Jose Cela's son, Jose Cela Conde, during the opening of the exhibition 'El recuerdo mas cercano' – which means "The closest memory" which is held at the Cervantes Institute. The exhibition is on until 23 October and celebrates the centenary of the birth of the Spanish author who won a Nobel Prize in 1989 for Literature.

Queen Letizia will make another appearance tomorrow (9 September) for an audience hearing at Zarzuela Palace.
