1830-1840: The dress coat, as this style of jacket was originally called in the late 18th century, was worn for day and formal evening occasions, with the exception of court which had its own prescribed dress code. Near the end of the 18th century and the first few decades of the 19th century this style of jacket was paired with contrasting colored knee breeches or trousers and a contrasting vest. By the 1820s, a matching suit, such as this one, was more common.
