The justacorps — from the French juste au corps, “close to the body” — was the long coat that defined men's dress from the 1660s to the later eighteenth century. Knee-length, fitted through the waist and flaring into stiffened skirts, it was worn with a waistcoat and breeches in the three-piece arrangement that leads directly to the modern suit.
The style crystallised at the court of Louis XIV of France, where the King used splendid, regulated dress as an instrument of rule. From Versailles it spread across Europe, structuring 1700–1750 fashion and remaining the formal coat well into 1750–1795 fashion.
Cut and Construction
A justacorps of the 1680s and 1690s reached the knee, fastened down the front with closely set buttons — many of them decorative, the coat often worn partly open over a long waistcoat — and carried enormous turned-back cuffs, low pockets with deep flaps, and skirts stiffened with buckram or horsehair so they stood away from the legs. Early examples were collarless; a small standing collar appeared in the eighteenth century.
The finest were of velvet or rich wool, embroidered down the fronts and cuffs with gold or silver thread, the buttons themselves of gilt metal, enamel, or covered silk. Livery and military justacorps translated the same cut into regimental colours with contrasting braid, fixing the visual grammar of the uniform coat.
Court, City, and Uniform
At court the justacorps was the required dress of a gentleman; its cost in cloth, braid, and buttons announced rank as surely as a title. The justaucorps à brevet, a blue coat with special embroidery, was granted by Louis XIV as a coveted mark of favour. In the city, merchants and professionals wore plainer versions in dark cloth, and the cut's discipline spread into everyday male dress.
Through the 1700s the coat grew slimmer, its skirts narrower and cuffs smaller, and the waistcoat shortened beneath it, but the essential silhouette — fitted torso, flared skirt, decorated front — held for a century.
From Justacorps to Suit Coat
In the later eighteenth century the formal justacorps relaxed into the frock coat and the cutaway tail coat, and the nineteenth century shortened the line into the lounge jacket. Yet the inheritance is plain: the modern suit coat keeps the justacorps' fitted waist, front buttons, cuffed sleeves, and the three-piece logic of coat, waistcoat, and legwear that Louis XIV's court standardised.
Women borrowed the justacorps as well. The tailored riding habit of the late seventeenth and eighteenth centuries copied its fitted body, deep cuffs, and braided fronts, making the coat one of the earliest examples of menswear tailoring deliberately adopted into female dress — a borrowing fashion has repeated ever since.
