Like most stylish royals, Queen Letizia [1] always manages to give polished, professional looks a bit of personal flair. But while we're used to her swapping blazers for capes [2] or rocking leather pants [3], her latest ensemble proves that even the most modest and classic of styles can be fun, too. It just depends on how you style them.

Attending a presentation for FameLab España 2016 Scientific Monologues, Letizia opted to go navy on navy, pairing a midlength skirt with a matching top. But rather than keeping her outfit super simple, a single throwback detail — a subtle peplum design — really took things to the next level, accentuating her waist and making us want to revisit the trend.

Take a look at Letizia's outfit ahead. Then check out more aughts trends you should reconsider [4].
