Argyle is a geometric, crisscross pattern of both intercrossing diagonal lines and repeating solid diamonds. Usually the pattern is composed of outlines that overlap varicolored diamonds, with the corners of the outlines meeting at the center of solid diamonds. Adapted from the tartan plaids of 17th-century Scotland, argyle was favored after World War I for knitted garments such as sweaters and socks, before appearing in textiles, wallcoverings, and other interior categories.
