A vest is a type of clothing that is worn on the upper body, typically without sleeves. It can be made from various materials, such as cotton, wool, or synthetic fabrics. Vests are often worn over a shirt and can serve different purposes, including fashion, warmth, or as part of a uniform. There are several styles of vests, including waistcoats, which are often worn in formal settings, and puffer vests, designed for warmth in colder weather. Some vests also have pockets and can be used for practical purposes, such as carrying small items while hiking or working.
