A snood is a type of headgear, worn by women over their long hair. It resembles a closefitting hood worn over the back of the head. The band covers the forehead or crown of the head, goes behind the ears and under the nape of the neck. A sack of sorts dangles from this band, covering and containing the fall of long hair gathered at the back of the head. A snood is sometimes made of solid cloth, but sometimes of loosely knitted yarn, or other net-like material.

While snoods first came into fashion in the 19th Century, they became popular again in Europe during World War II. At that time, the British government had placed strict rations on the amount of material that could be used in clothing. While headgear was not rationed, snoods were favored, along with turbans and headscarves, in order to show one's commitment to the war effort.
