A cardigan is a type of knitted sweater that opens in the front, typically featuring buttons or a zipper. It is often made from materials like wool, cotton, or synthetic fibers, making it versatile for different weather conditions. Cardigans come in various styles, lengths, and colors, appealing to a wide range of fashion preferences. Originally popularized in the 19th century, the cardigan is named after James Brudenell, the 7th Earl of Cardigan, who led the Charge of the Light Brigade. Today, cardigans are a staple in many wardrobes, suitable for both casual and formal occasions, and can be layered over shirts or dresses.
