Surtouts are a form of outerwear that originated in the 18th century and were typically worn over a man's suit jacket. Surtouts were designed to provide extra warmth and protection from the elements. Today, they are rarely worn, but the word has several synonyms that can be used in modern contexts. Overcoat, topcoat, and trench coat are some of the synonyms for "surtouts". These words describe an outerwear that is worn over clothing, typically to provide warmth and protection from weather. While these words may not be commonly used in everyday conversation, they can be useful to know if you are discussing fashion or clothing trends.
