The first form of the redingote was in the 1700s, when it was used for travel on horseback. This coat was a bulky, utilitarian garment. It would begin to evolve into a fashionable accessory in the early 1800s, when women began wearing a tighter-fitting, princesse-cut versions. Italian fashion also picked it up (the redingotte), adapting it for more formal occasions.
The redingote à la Hussar was trimmed with parallel rows of horizontal braid in the fashion of Hussars' uniforms.
The style continued to evolve through the late 19th century, until it took a form similar to today's redingote. The newer form is marked by a close fit at the chest and waist, a belt, and a flare toward the hem.
The men's redingote was an 18th century or early 19th century long coat or greatcoat, derived from the country garment with a wide, flat collar called a frock In French, redingote is the usual term for a fitted frock coat. The form a men's redingote took could be of the tightly fitting frock coat style, or the more voluminous, loose "great coat" style, replete with overlapping capes or collars, such as a "garrick" redingote.
