A pillowcase is a covering that you slip over your pillow/s that matches your sheets/bed linens. It is rectantular in shape and open on one of the narrow sides to slip the pillow in/out. In the US, there are three sizes: the small size if called Standard; the medium size is called Queen; and the large size is called King.
