Queen Letizia of Spain looked positively radiant in a belted denim dress at the Retina Eco Awards in Madrid on Thursday, Sept. 19. Frankly, I'm convinced the stylish wife of King Felipe could make a trash bag look like couture.

Queen Letizia of Spain has captured my attention on multiple occasions for her ability to look professional in whatever she wears. So, you can imagine my surprise when I saw the 52-year-old monarch made a denim dress appear royally chic.

King Felipe 's wife looked so youthful in a brand new Carolina Herrera A-line dress made from an unexpected dark wash denim. The crew-necked number featured a seam pinstripe and a belted waistline for a vintage silhouette. The garment, which featured a floaty skirt, was teamed with a pair of crimson kitten heels from Magrit.

She was often regarded as the most fashionable contemporary monarch. Now, Queen Letizia has put the final touch on her reputation by demonstrating that she can experiment with fashion and set trends.
