After missing the mark with tricky tailoring last season, Kim Jones did exactly what he was presumably hired to do: Give a young point of view to the classic clothing and travel accessories that are at the core of the British brand. He opened with a navy blazer paired with gray flat-front trousers rolled up above the ankle. Each exit that followed featured tailored pieces, but with a fresh attitude that oscillated between sharply cut suits — some with Prince of Wales checks or fine pinstripes — and what Dunhill called “elegantly disheveled” washed linen looks. Shiny aluminum suitcases inspired by the Twenties were ultralight for today’s frequent flyers, while scratch-resistant carbon fiber bags were among the technical materials that gave the once-dusty heritage brand a forward-looking veneer.
