Pringle of Scotland
Argyle knitwear became fashionable in Great Britain and then in the United States after the First World War of 1914–1918. Pringle of Scotland popularised the design, helped by its identification with the Duke of Windsor. Pringle's website says that "the iconic Pringle argyle design was developed" in the 1920s. The Duke, like others, used this pattern for golf clothing: both for jerseys and for the long socks needed for the plus-fours trouser fashion of the day.
