Couture meets utilitarianism with the Cube, MaxMara’s new frigid-weather hybrid. The Italian line’s ingenious invention features a flock of add-on accessories (fox and mink collars and cuffs, belts, hoods, and shrugs) for a reversible parka available in four lengths and six colors. Bonus: The coat’s sumptuous Siberian goose down filling is so microcompressible it easily packs into (you guessed it) a cube-shaped tote—just like a luxe little sleeping bag. Prices vary. Available at MaxMara (900 N. Michigan Ave.; maxmara.com).
