A woollen garment is a type of clothing made from wool, which is a natural fibre obtained from sheep and other animals. A JUMPER is a type of woollen garment that is typically knitted, meaning it is made by interlocking loops of yarn. It is usually worn over a shirt or blouse and is often used as a form of casual wear. A KNIT is another type of woollen garment, which is made by interlocking loops of yarn in a process similar to knitting. Knits are usually thicker and more durable than jumpers, and are often used for winter wear.
