A cardigan is a type of knitted sweater that opens in the front, typically featuring buttons or a zipper. It is usually made from wool, cotton, or synthetic fibers, making it a versatile garment suitable for various weather conditions. Cardigans come in different styles, lengths, and colors, allowing for a wide range of fashion choices. Originally popularized in the 19th century, the cardigan is named after James Brudenell, the 7th Earl of Cardigan. This garment can be worn over shirts, blouses, or dresses, making it a staple in many wardrobes. Cardigans are often used for layering, providing warmth and comfort without being overly bulky.
