A coverall is a type of garment that covers an individual's entire body, typically made from durable material such as denim or canvas. It can be worn for various purposes including work, play, and protection. Coveralls are often used in industries where there is a risk of contamination or exposure to hazardous materials, providing a barrier between the individual and the environment they are working in. They may also be worn during activities such as painting, construction, or other tasks that require full-body protection from dirt or debris.
