Often made from durable materials like cotton or polyester, smocks are commonly used in various settings, including art studios, kitchens, and laboratories. They can have long or short sleeves and may feature pockets for convenience. Smocks are popular among artists, such as painters, who need to keep their clothes clean while working with messy materials. In educational settings, children often wear smocks during art classes to prevent spills on their everyday clothes. Overall, smocks serve a practical purpose in many creative and professional environments.
