Céline's Phoebe Philo is nothing if not an innovator. The designer behind minimalist reinvention does it again for Fall 2017, giving us workwear, redefined. Oversize suiting and broad-shouldered trench coats dominate, then button-down sheaths, tapered at the waist and worn over pants. She riffs on the familiar — a pair of tailored trousers with a slit at the knee, just like your favorite boyfriend jeans. Clothes for an executive who's a fashion girl at heart.
