Mod is a youth style that arose in late-1950s–1960s Britain and became a symbol of Swinging London. The name comes from 'modernist'. Mod celebrated clean lines, graphic quality and futuristic freshness: geometric patterns, black-and-white contrasts, bright colour blocks, short A-line dresses, mini skirts (whose invention is credited above all to Mary Quant in London and André Courrèges in Paris), go-go boots and neat suits for men. The style icon was the model Twiggy with her boyish haircut and big eyes. Mod was about modernity, music (modern jazz, rhythm and blues, soul, ska), scooters and the cult of youth. It is a style of optimism, dynamism and the 'space age' of the 1960s. Mod returns regularly to modern fashion with its geometric prints, minis and clean, graphic aesthetic. It is an eternal symbol of youthful, confident and modern freshness.
