Parties, premieres, and galas: Fall is in full swing, and so are the world’s most stylish in dramatic looks that run the gamut from old school to what’s next. In London, Adwoa Aboah channeled a modern-day Marilyn Monroe in Miu Miu’s bejeweled pink satin halter dress, cunningly paired with Prada’s orange sandals. In New York, Emma Stone lit up the Maniac premiere in “lampshade” Givenchy, while in Madrid, Queen Letizia of Spain was a thoroughly modern monarch in Pedro del Hierro’s midnight blue jumpsuit. At the Mercury Prize (yes, back in the U.K.), Jorja Smith wore decidedly grown-up fringe by Jean Paul Gaultier. And in Los Angeles, it was Jessica Biel who proved that fashion lightning can strike twice—first, on the red carpet at the Emmys in cloud-like Ralph & Russo Couture, and then swapping it for a neon chartreuse, neo-Grecian dress to carry on late into the night.
