The 44-year-old royal is a huge fan of wearing white and red together, like she did one month ago at the Reina Sofia Alzheimer Foundation 40th anniversary celebrations.
The Spanish royal is now back at it, wearing a tight pair of white trousers and a red top combination three days apart.
The first outfit, worn on June 23, featured a scarlet satin top with a high neck.
The royal, who has a stunningly svelte figure, teamed the top with very tight, high waisted trousers.
Letizia accentuated her height with a bright red sandal, as she attended the Join ‘Coworking Santander’ Programme in Santander, Spain.
Only three days later, today at ‘Toma La Palabra’ in Aviles, she wore a very similar look.
A pair of white, flared trousers were paired with a leather red jacket, with large buttons and a peplum.
Crimson stilettos with a pointed toe finished off the look.
Her hair was worn in a polished undo, with red lipstick accentuating her face.
On June 19 the Queen of Spain wore a pair of on-trend mules to an event at the Prado Museum.
Queen Letizia, 44, married Felipe VI of Spain in 2004.
The stunning brunette was born in Oviedo, Asturias, Spain and had a very different life before she met the king.
Far from royal roots, her grandfather was a mechanic and taxi driver.
Letizia herself was a successful journalist before she married Felipe when she was 32-years-old.
Express.co.uk revealed the surprising thing that Queen Letizia and Meghan Markle have in common.
Both women were married before they met their royal partners.
Letitzia was previously married to Alonso Guerrero Pérez, who was ten years her senior and a writer and high school teacher.
The pair were together for 10 years before they were married in a civil ceremony in 1998 at Almendralejo, in Badajoz.
