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 used as a layering piece, providing warmth or style without the bulk of a full jacket. They come in different styles, including casual, formal, and athletic. Vests can also serve specific purposes, such as in the case of safety vests worn by construction workers or life vests used for flotation in water activities. In fashion, vests are often paired with shirts or blouses to create a polished look.
