A goatee is a type of beard worn on the chin, much like a Billy Goat’s beard and is never supposed to be connected to a mustache. A proper goatee should have hair right below the lower lip and the standard size for a goatee has to be the same as the width of the beardsman’s mouth. To grow a goatee a beardsman must allow the hair below the lower lip to grow down into the part of the beard growing on the chin. The sides are then defined as vertical lines or slightly curved, based on the beardsman’s preference and the hair is then rounded off at the bottom of the chin.
