The term overcoat is a generalized term signifying a long coat worn over other items of clothing such as a suit or dress, uniform or even casual clothes. Overcoats extend below the knee over the shins 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 outer coats. Unlike overcoats topcoats are usually made from lighter weight cloth such as gabardine or covert, while overcoats are made from heavier cloth or fur. This is because overcoats are more commonly used in winter so warmth is more important.
