A mannequin is a doll, often articulated, used by artists, tailors, dressmakers, window dressers and others, especially to display or fit clothing and show off different fabrics and textiles. Previously, the English term referred to human models and muses ; the meaning as a dummy dating from the start of World War II.

Window dressers are retail workers who arrange displays of goods in shop windows or within a shop itself. Such displays are themselves known as "window dressing". They may work for design companies contracted to work for clients or for department stores, independent retailers, airport or hotel shops.
