What are 'plus fours', and how did they get that name?

Plus fours are one of those quintessentially British garments, immediately recognisable by their unique silhouette. The name itself gives the game away: they are cut to finish four inches below the knee, creating that signature billowy fold over the calf.

Originally finding favour on the golf courses and sporting estates of the 1920s, these trousers were designed for exceptional freedom of movement. Today, they stand as a hallmark of classic country style, a statement of sartorial confidence.
