*By Mark Large/Getty Images.*For the first time as a member of the British royal family, Kate Middleton makes her way onto the International Best-Dressed List—her inaugural appearance came in 2008, and a whirlwind of fashion successes since has earned her a nod this year. She’s captivated the world with her signature mix of high and low fashion. (For a look at Kate’s particularly fetching travel attire, see our slide show.) Michelle and Barack Obama also make their first appearance together on the Best-Dressed Couples list. Michelle has been among the best-dressed ladies for the past four years, while the president has only earned a spot once, back in 2009. (Other politicos: French First Lady Carla Bruni-Sarkozy makes the grade for the fourth time, but her husband, President Nicolas Sarkozy, does not. And other royals include Princess Charlene of Monaco, the King of Bhutan, Princess Alexandra of Greece, Countess Matilde Borromeo, Prince Antonius von Fürstenberg, Her Highness Sheikha Moza Bint Nasser of Qatar, and Nicolas Mirzayantz of Greece.)

Meanwhile, from Hollywood’s royal ranks come actors Justin Timberlake, Colin Firth, and Armie Hammer—all first-time entrants—while actresses Carey Mulligan and Tilda Swinton are second-timers. (Swinton returns after a three-year hiatus.) Among the fashion originals, Lady Gaga (her second recognition) is joined by Janelle Monáe—and NBC News anchor Brian Williams enters the illustrious ranks of the list’s Hall of Fame.A sneak-peek at the 72nd annual International Best-Dressed List:
