A corduroy is a rough fabric, which has velvet-like longitudinal ribs. Depending on the width of the longitudinal ribs, a corduroy fabric is named differently, from baby corduroy (decidedly fine ribs), genoa corduroy (medium width ribs), wide corduroy (very wide ribs) to fancy corduroy (different width ribs), each rib width can be named differently.
Corduroy is mainly worn in autumn and winter, because the fabric warms well. Other advantages that the fabric corduroy brings are air permeability and insensitivity to dirt. It is usually made of eighty to ninety percent cotton and is mainly used for pants, skirts and jackets. The first corduroy trousers ever produced were made in Manchester, thus corduroy is sometimes referred to as "Manchester".
