I know what Keri Russell's The Diplomat character would wear to the Season 3 premiere (if she wasn't fictional): the actor's exact red carpet look on October 14, down to the wide-leg trousers.
Binge-watching both seasons in under a week gave me a unique understanding of Kate Wyler's on-screen style. Dresses and skirts are mostly off-limits for the ambassador, only to be worn at galas with black-tie dress codes. Kate prefers menswear-inspired suits—in neutral shades, of course—while patching up the United Kingdom's relationship with the United States.
