A handlebar mustache is a distinctive facial hairstyle characterized by full, often dense growth along the upper lip, with the outer corners extending beyond the mouth and typically curled upward and sometimes slightly forward, forming the iconic "handle" shape.
This style has roots in military tradition, circus culture, and early 20th-century popular imagery, enduring as a symbol of bold individuality and curated aesthetic.
