Mod is a 1960s British youth culture built on clean lines, geometric patterns, and modernist influence, born in London where mods rode scooters and adopted European style in opposition to rocker subculture. Geometric mini dresses are the core garment. Sleek straight-cut shifts cover the same ground. Color-blocked coats go over them. Go-go boots go below, with bold-print tights underneath and PVC accessories throughout.
