A sweater is a knitted garment typically worn on the upper body for warmth and comfort. Made from a variety of materials, including wool, cotton, acrylic, and blends, sweaters come in various styles, such as pullovers, cardigans, and turtlenecks. They can feature different patterns, textures, and designs, from simple solids to intricate cables or stripes. Sweaters are versatile pieces of clothing, suitable for layering during colder weather or as standalone pieces in mild temperatures. Their cozy, casual appeal makes them a staple in both everyday and more formal wardrobes, offering both style and practicality.
