In the context of hairstyles, the usage of the term pigtail (or twintail or twin tail) shows considerable variation. The term may refer to a single braid, but is more frequently used in the plural to refer to twin braids on opposite sides of the head. For some people, the term "pigtails" applies whether or not the hair is braided, but there is not widespread agreement on this (in places where this usage is common, unbraided pairs are called bunches and a single bunch, regardless of position on the head, is called a ponytail).
