Mismatch

A touch of mismatch between items of clothing brings depth to a day's look. The pop of color of an accent piece. The shine of a bag against a matte coat. A silk scarf on a cable-knit sweater. A patterned shirt under a solid suit.

Contrast and compliment. As the saying goes, the only two things that should match are your shoes and your socks.

Grey flannel trousers. Brandy calf oxfords. Patterned cotton socks.
