A variation of side ponytail, similar to short ponytail, where the gathered hair is notably shorter than normal. Usually stops halfway between the top of the head and the chin.
Not to be confused with one side up, which also has hair tied on the side but it lets some hair fall loosely. In a side ponytail the majority of one's hair—save for sidelocks—is pulled up into a ponytail that leaves no hair falling loosely.
