It's already been a busy month for the Spanish royals and there was no let-up for Queen Letizia and King Felipe VI as they visited the Madrid-based headquarters of the National Center for Cardiovascular Research (CNIC) today.
Queen Letizia stepped out in her favourite Hugo Boss leather dress for a tour of the research facilities.
The burgundy lambskin sheath dress has been a popular choice for Letizia since she first sported it in October 2014 for a solo visit to Vienna.
Today Letizia combined the dress with her BOSS Fashion Show 'FS_Jesila' blazer which she also debuted in Vienna.
She also brought back her familiar LODI 'Sara' ombre patent pumps and TOUS gold long dangle earrings.
Letizia pepped up the ensemble with a new burgundy croc-embossed handbag featuring a gold curb chain.
These are the best images I could find of the bag, and after an extensive search I was able to identify it from the archives of Uterque.
The bag has a croc-embossed body with an ostrich pattern trim. It retailed for €150.
The King and Queen of Spain attended a dinner this evening commemorating the 30th anniversary of the Spanish newspaper, Expansión.
Queen Letizia looked sophisticated in a new Carolina Herrera number for the event held at the The Westin Palace hotel in Madrid, which was attended by three hundred guests from the economic, business, academic and institutional sectors.
She wore a set from the designer's Pre-Fall 2015 collection featuring a top with feather and bead applique on the sleeves, and a matching pencil skirt.
Letizia kept her accessories simple but made a statement with a new pair of dazzling diamond and ruby chandelier earrings, which she complemented with cherry red lipstick. Unfortunately we don't know the origin of these sparkling beauties.
Here's a closer look at her Felipe Varela satin clutch bag and black LODI straight-cut vamp patent pumps.
Letizia swept her hair up in a side braided up-do.
Following a weekend vacation at a ski resort, it was back to work for the King and Queen of Spain on Monday. The royal couple attended the 2016 Innovation and Design Awards in Madrid.
Their Majesties delivered the prizes which are Spain's highest recognition of companies and professionals who excel in the fields of design and innovation.
Queen Letizia made quite the impression in an olive green cape dress as she arrived for the event held at the Regional Archaeological Museum of the Community of Madrid.
The contemporary piece was a fitting choice for the awards ceremony as it represented innovative design. So is it a dress, or is it a cape? From what we can see, it's a cropped sleeve sheath dress with an attached cape-coat.
Unfortunately we still don't know the designer of this superhero-inspired piece.
Letizia offset the cape dress with snake skin accessories. She carried a new python clutch handcrafted by Spanish brand Lidia Faro. On her feet she wore the Magrit 'Mila' snake-effect pumps.
The Queen debuted a new pair of silver ear cuff earrings featuring small pearls and crystals. The brand/designer is unknown.
The Spanish royal family headed to the ski slopes this weekend.
The family of four posed for an official photocall during their short winter break at the Astún ski resort situated in the High Aragon of the western Pyrenees, near the French border.
Queen Letizia opted for all-black ski gear which contrasted perfectly against the snow white backdrop.
She wore the Bogner 'Mabel-D' ski jacket, a high-performance waterproof jacket insulated with 650-fill power white goose down.
She also wore the Bogner 'Freeride' Ski Helmet and ski googles by Swans.
Queen Letizia chaired the sixth annual Forum Against Cancer meeting in Madrid today, organized as part of the events to mark World Cancer Day, on February 4th.
In her role as honorary president of the Spanish Association Against Cancer (AECC), Her Majesty delivered a speech to open the session.
Queen Letizia premiered an elegant grey structured suit with a futuristic flair from her go-to brand, Hugo Boss.
The separates include the BOSS 'Jadela' Stretch Virgin Wool Asymmetrical Blazer (US$625) teamed with the matching BOSS 'Tiluna' Stretch Virgin Wool Dress Pants (US$275).
Letizia accessorized the set with her black Carolina Herrera metal bar flap clutch bag and Magrit charcoal suede platform pumps.
She finished the look with her beloved gold filigree hoop earrings.
Today's look was consistent with the executive tone of previous years:
