A woman’s dress, typically loose-fitting and informal, or a man’s frock coat—a term that has migrated across genders, centuries, and social classes, attaching itself to entirely different garments at different moments in history.
Originally, a frock was a coarse outer garment worn by laborers in medieval England. By the seventeenth century, it had been adopted by the military as a soldier’s coat, loose and unadorned. In the eighteenth century, the frock coat emerged as a fitted, knee-length garment for men, with a waist seam and full skirt, which became the standard of formal male dress in the nineteenth century.
Simultaneously, the frock evolved in women’s dress as a loose, informal gown. The term suggested ease and domesticity: a frock was not a dress for ceremony but for daily life. In children’s wear, the frock was a one-piece garment that allowed freedom of movement, and the term persists today in the school uniform’s “frock.”
The frock demonstrates the instability of fashion terminology. A word can move from laborer to soldier to aristocrat to child, attaching to different garments at each stop. What unites all these meanings is the frock’s original character as a garment of relative simplicity—less structured, less formal, less expensive than the grander garments it coexists with.
