Queen Letizia, 45, was spotted at the Zarzuela Palace meeting with the Royal Academy of Engineering in Madrid.
Seen without her husband, she joined the members of the academy in a chic look that highlighted her trim shape.
The elegant look featured fitted black trousers with matching black stilettos which elongated her legs.
She finished the look with a tweed fitted long-sleeved top in a Chanel-esque style.
The mum-of-two showed off her slim waist and long legs with the elegant look.
She accented the smart look with a sleek blowdried bob and subtle make up.
Some simple pearl earrings were the only pieces of jewellery she was wearing.
Queen Letizia added some cheeky red nail varnish to the look, matching her previous outfit from last week.
She was previously spotted in Madrid last week whilst attending the International Contemporary Art Fair.
This time she went for a much sexier look as she dressed head to toe in red.
The long-sleeved red blouse had blouson arms and a nipped in waist, whilst tucked into a matching knee length red skirt.
Her hair was pinned back in an elegant updo.
