2004
Letizia was a radiant bride when she wed Felipe in May 2004.
Her off-white silk wedding dress was from Spanish couturier Manuel Pertegaz.
The elegant long-sleeved bridal gown boasted a high stand collar and it was trimmed with heavy white embroidery depicting the fleur de lys and ears of wheat, which nodded to the Prince of Asturias crest.
The bride completed her look with a lace veil and the same diamond tiara her mother-in-law Queen Sofia sported on her wedding day.
