In the 1920s, a type of patterned knitwear emerged in Great Britain. Argyle knitwear became fashionable there and then in the United States after World War I. The Pringle family made popular this design, which was later associated with the Duke of Windsor. Argyle is a diamond pattern, usually made of lozenges or diamonds. It is also sometimes called tartan plaid. The word "argyle" may refer to an individual diamond in the design, but more commonly refers to the overall pattern. The name comes from the Scottish town where the fabric was first produced. Most argyle contains layers of overlapping motifs, adding a sense of three-dimensionality, movement, and texture.

National Argyle Day is celebrated every year on January 8th!

Keely McAleer founded this dimensional textile celebration in 2008.
