What is pencil mustache?

A pencil mustache is a narrow, neatly groomed mustache that is typically worn above the upper lip. It gets its name from its resemblance to a thin line drawn with a pencil. This style of mustache became popular in the early 20th century and has been associated with elegance, sophistication, and refinement. Some famous figures that have sported a pencil mustache include Clark Gable, Errol Flynn, and John Waters. It requires regular maintenance to keep it looking sharp and well-defined, as it can easily become unkempt if not properly groomed.
