Historically, the term "pocket" referred to a pouch worn around the waist by women in the 17th to 19th centuries. Skirts or dresses of the time had an opening at the waistline to allow access to the pocket which hung around the woman's waist by a ribbon or tape. The opening in the skirt was formed by leaving unstitched, near the waist, the panels of fabric for the skirt. Fabrics could be around 20 inches wide, so seaming the selvedges offered a reliable opportunity for an opening. Corresponding opening in the panels of fabric forming the petticoat underneath. The rhyme was first recorded by
James Orchard Halliwell in 1842, but there is evidence that it was popular in Britain and America at least in the early nineteenth century. Various persons have been identified with Lucy Locket and
Kitty Fisher. Halliwell suggested that they were "two celebrated courtesans of the time of Charles II", but no supportive evidence has been found. ==Notes==
