A coat is a long garment worn by both men and women, for warmth or fashion. Coats typically have long sleeves and open down the front, closing by means of buttons, zippers, hook-and-loop fasteners, toggles, a belt, or a combination of these. Other possible ornaments include collars and shoulder straps.
An early use of coat in English is coat of mail (chainmail), a tunic-like garment of metal rings, usually knee- or mid-calf length.
The medieval and renaissance coat (generally spelled cote by costume historians) is a midlength, sleeved men's outer garment, fitted to the waist and buttoned up the front, with a full skirt: in its essentials, not unlike the modern coat.
By the eighteenth century, overcoats had begun to supplant capes and cloaks as outer wear, and by the mid-twentieth century the terms jacket and coat became confused for recent styles; the difference in use is still maintained for older garments.
In the early nineteenth century , coats were divided into under-coats and overcoats. The term under-coat is now archaic but denoted the fact that the expression coat could be both the outermost layer for outdoor wear (overcoat) or the coat worn under that (under-coat). However, the term coat is increasingly beginning to denote just the overcoat rather than the under-coat. However, the older usage of the word coat can still be found in the expression "to wear a coat and tie", which does not mean that wearer has on an overcoat. Nor do the terms tailcoat' or morning coat denote types of overcoat. Indeed, an overcoat may be worn over the top of a tailcoat. In tailoring circles, the tailor who makes all types of coats is called a coat maker. Similarly, in both British and American English, the term sports coat is used to denote a type of jacket not worn as outerwear (overcoat).
The term jacket is a traditional term usually used to refer to a specific type of short under-coat. Typical modern jackets extend only to the upper thigh in length, whereas older coats such as tailcoats are usually of knee length. The modern jacket worn with a suit is traditionally called a lounge coat (or a lounge jacket) in British English and a sack coat in American English. The American English term is rarely used today. Traditionally, all men dressed in a coat and tie, although this has become gradually less widespread since around the 1960s. Because the basic pattern for the stroller (black jacket worn with striped trousers in British English) and dinner jacket (tuxedo in American English) are the same as lounge coats, tailors traditionally call both of these special types of jackets a coat.
An overcoat is a long coat (at least mid-calf) designed to be worn as the outermost garment worn as outdoor wear; while this use is still maintained in some places, particularly in Britain, elsewhere the term coat is commonly used mainly denote only the overcoat, and not the under-coat. A topcoat is a slightly shorter overcoat, if any distinction is to be made. Overcoats worn over the top of knee length coats (under-coats) such as frock coats, dress coats, and morning coats are cut to be a little longer than the under-coat so as to completely cover it, as well as being large enough to accommodate the coat underneath.
Some of these styles are still worn. Note that for this period, only coats of the under-coat variety are listed, and overcoats are excluded.
