Kidman, who turned 55 this summer, flexes her impossibly sculpted triceps on the magazine’s cover — a cascade of red hair falling over one shoulder with a section cropped bluntly at her chin. Not a power suit or black turtleneck in sight: Kidman is styled in pieces from fashion brand Diesel’s Autumn-Winter 2022 collection, which debuted at Milan Fashion Week this February — a highly praised array replete with Y2K-inspired trucker hats, denim trench coats and the buzzy belt-skirt Kidman wears.
