The vest is a garment worn on the upper body and must be close fitting. It lacks sleeves and more often than not, ends near the waist. Any given vest can be simple or ornate or for leisure or luxury. Historically, the vest can be worn either in the place of or underneath a larger coat dependent upon the weather, wearer, and setting. Sometimes though, a vest is worn over a short or long sleeve shirt. There are many types of vests, made of a wide variety of materials, those of which serve various functions and purposes and allow for variation both within cultures and cross-culturally. A vest might be closed in the front and pulled on over the head or can contain various frontal material like buttons or zippers.
