This is a Fair Isle knit sweater from Margaret Howell. It was very popular even before its release and quickly sold out, making it a valuable piece. It's made of a light, fluffy material using the natural colors of wool in a black and white two-tone design. It features a timeless Fair Isle pattern. It's made using a whole garment knitting technique, so it has no seams and is easy to wear. The tag has been removed, but it is new and unused.
