By the 19th century, mourning behaviour in England had developed into a complex set of rules, particularly among the upper classes. For women, the customs involved wearing heavy, concealing black clothing, and the use of heavy veils of black crêpe. The entire ensemble was colloquially known as "widow's weeds" (from the Old English , meaning "garment"), and would either be newly-created clothing, or overdyed clothing the mourner already owned. Up until the later 18th century, the clothes of the deceased, unless they were considerably poor, were still listed in the inventories of the dead, as clothing constituted a relatively high expense.
