Sweater types are a popular type of clothing for colder weather. KNIT sweaters are made from interlocking loops of yarn and can be lightweight or heavy depending on the type of yarn used. ANGORA sweaters are made from the fur of ANGORA rabbits and are known for their softness and warmth. PULLOVER sweaters are designed to be pulled over the head and typically have a round neckline. Crewneck sweaters have a round neckline that sits close to the neck and are usually made from thicker materials. Turtleneck sweaters have a high neckline that folds over and covers the neck. CARDIGAN sweaters are open-front sweaters that are fastened with buttons or zippers. V-neck sweaters have a neckline that is shaped like a 'V' and can be worn with a collared shirt underneath. Pullon sweaters are similar to PULLOVER sweaters but do not require the wearer to pull them over their head. Slipon sweaters are designed to be slipped on and off without having to pull them over the head.
