What is brush moustache?

The brush moustache is a style of facial hair where the hair is grown thick and long above the upper lip, resembling a brush. The moustache is typically sculpted with a small gap between the hair on either side of the nose. This style of moustache became popular during the early 20th century and was often worn by men in the military or as a mark of sophistication. Notable men who have worn the brush moustache include former United States president Theodore Roosevelt and silent film star Charlie Chaplin. The style has recently seen a resurgence in popularity among hipsters and men interested in vintage fashion.
