For those who had doubts about Queen Letizia of Spain's role as a trendsetter, there's this outfit. Sure, it might look simple at first glance — white cigarette pants and a white blazer, what's so special? — but it's all about the details when it comes to this look, in which the always-stylish royal proved that rule about not wearing white once Summer comes to an end is just silly.
Pairing her perfectly hemmed loose pants (which hit just below the top of her heels) with pointy nude shoes allowed her to add a little touch of fun with a star-printed top, while still keeping the look totally professional as she led a forum on cancer research in Barcelona. Add to that her gorgeous bouclé blazer, and we really can't think of what else she needed to do to make this a great work-appropriate outfit.
