Young Curly Brunette Girl Posing With A Mannequin

Historically, artists have often used articulated mannequins as an aid in drawing draped figures. The advantage of this is that clothing or drapery arranged on a mannequin may be kept immobile for far longer than would be possible by using a living model.

Medical simulation mannequins, models or related artefacts such as SimMan or Harvey are widely used in medical education. These are sometimes also referred to as virtual patients.
