Winter coat

A coat is a garment worn by both men and women, for warmth or fashion. Coats typically have long sleeves and are open down the front, closing by means of buttons, zippers, hook-and-loop fasteners, toggles, a belt, or a combination of some of these. Other possible features include collars, shoulder straps and hoods. Persians were the first people that made coats.
History
The medieval and renaissance coat (generally spelled cote by costume historians) is a mid-length, 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 outerwear, 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.

Coats, jackets and overcoats
In the early 19th century, coats were divided into under-coats and overcoats. The term under-coat is now archaic but denoted the fact that the word coat could be both the outermost layer for outdoor wear (overcoat) or the coat worn under that (under-coat). However, the term coat has begun to denote just the overcoat rather than the under-coat. 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, morning coat or house 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 American English, the term sports coat is used to denote a type of jacket not worn as outerwear (overcoat) (sports jacket in British English).
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. Traditionally, the majority of men dressed in a coat and tie, although this has become gradually less widespread since
