Kate and Letizia are often comparable when it comes to their fashion choices, and both royals seem to have traded their effortless summer gowns for smarter tailored looks this autumn.
The pair have been spotted in jackets, long-sleeve tops, and trousers as of late, after months of donning brightly coloured chiffon, linen and silk ensembles.
It’s not the first time the royal women have pioneered the latest fashion trends. Earlier this year, both Kate and Letizia were spotted wearing striking pink power suits complete with smart tailoring.
Their inspired sartorial style is noticeable in their mutual love for straight-leg and cigarette-style trousers, and long-line, double-breasted blazers.
Both royals are fans of the tonal look too, often spotted in coordinating shades no matter whether they’re wearing trousers, skirts, jackets, dresses, or even regal gowns.
Queen Letizia and Princess Kate recently stepped out in similar textured grey blazers and smart black trousers.
While attending the opening of the Professional Training Course, the Spanish royal wore the Long Jacket with Gold Buttons by Massimo Dutti (£145).
She teamed the statement garment with black leather slingback pumps by the same designer and a pair of Chanel Comete Earrings, which retail for a staggering €6,800 (£5,841).
Earlier today, Kate donned a very similar outfit while in Hereford, wearing a double-breasted houndstooth tweed blazer by the fashion atelier Maje Paris (£379).
She teamed the garment with tight-fitting black trousers just like Queen Letizia and finished the look with some chunky ankle boots by the designer, See By Chloe (£358).
