Overcoat

An overcoat is a type of long coat intended to be worn as the outermost garment, which usually extends below the knee. Overcoats are most commonly used in winter when warmth is more important.

They are sometimes confused with or referred to as topcoats, which are shorter and end at or above the knees. Topcoats and overcoats together are known as outercoats. Unlike overcoats, topcoats are usually made from lighter weight cloth such as gabardine or covert, while overcoats are made from heavier cloth or fur.

History
In many countries, coats and gowns reaching below the knee have been worn for centuries, often for formal uses, establishing either social status or as part of a professional or military uniform. In the 17th century, the overcoat became widely stylized and available to the different classes.

In the Western world, the general profile of overcoats has remained largely unchanged for a long time. During the Regency, the fashion was to have very form-fitting clothes, with sidebodies, waist seams, and a flared skirt. Examples of this included the frock overcoat and paletot.
