Plus-fours are breeches or trousers that extend 4 inches (10 cm) below the knee (and thus four inches longer than traditional knickerbockers, hence the name). As they allow more freedom of movement than knickerbockers, they have been traditionally associated with sporting attire from the 1860s and onward, and are also particularly associated with golf.
They are also associated with bicycle fashion in the 50s and 60s in Great Britain.
An "extravagant, careless style that fit right in with the looser fashions and lifestyles of the 1920s," plus-fours were introduced to America by Edward, Prince of Wales (later Edward VIII), during a diplomatic trip in 1924. They are often seen on golf courses, and frequently worn with argyle socks, silk neckties, and dress shirts/sweaters. Some plus fours even came as complete suits.
Also mentioned in The Magicians Land, Book Three of The Magicians series by Lev Grossman.
They are worn by the character Rufus Maleficarus in Johannes Cabal the Necromancer by Jonathan L. Howard.
