Overcoat

An overcoat is a type of long coat intended to be worn as the outermost garment. Overcoats usually extend below the knee, but are sometimes mistakenly referred to as topcoats, which are short coats that 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, because overcoats are more commonly used in winter when warmth is more important.
