"a thick Arran jumper that "
is a style of jumper that takes its name from the Aran Islands off the west coast of Ireland. It is sometimes known as a fisherman sweater. A classical fisherman's sweater is a bulky garment with prominent cable patterns on the chest, often cream-colored. Originally the jumpers were knitted using unscoured wool that retained its natural oils (lanolin) which made the garments water-resistant and meant they remained wearable even when wet. It was primarily the wives of island fishermen who knitted the jumpers.
