Young Skinny Brunette Girl With Pigtails On The Rural Village Road With A Scarf

Robert Louis Stevenson mentions "pigtail" referring to hair and then to "pigtail tobacco" in the first and fourth chapters of Treasure Island, respectively.
Most dictionaries still define "pigtail" as a single tight braid. However, many American English speakers use the term to describe two symmetrical bunches of hair on either side of the head, braided or not. In some cases, the term only applies to unbraided hair. This usage of the term can be seen on personal and professional websites devoted to hairstyles or even by typing "pigtails" into a search engine.
