The argyle print originated in Argyll, Scotland, worn by the high clansmen of the family Campbell, and dates back as early as the 17th century.
It appeared as a type of tartan, which refers to the pattern of crisscrossed lines displayed on cloth, i.e. what we Americans refer to as plaid.
They used it on their kilts, plaids, and socks. (For a Scotsman, a plaid is a cloth or blanket slung over the shoulder).
Supposedly, the first argyle sweater was created sometime in the 1920’s by Pringle of Scotland, a luxury knitwear manufacturer and importer.
However, the print did not become considered high fashion until after World War I.
One source claims that it was the president of Brooks Brothers, having returned from a golf tournament held in Scotland, who presented the U.S. with the argyle pattern.
