krillin's appearance stays relatively the same for the majority of the series. he is first introduced at age 13, with a shaved head and still dressed in the yellow-and-orange clothing worn at the monastery at which he had been training. he does not possess a visible nose, and has six spots of moxibustion burns on his forehead, a reference to the practice of shaolin monks. toriyama once stated, seemingly humorously, that krillin's lack of a nose is because he has a "physical idiosyncrasy" that allows him to breathe through the pores of his skin. later, he wears the orange "gi" uniform that is presented to both himself and goku by kame-sen'nin in honor of their first martial arts competition. occasionally he is seen in casual clothes, but for the most part continues to dress for training or fighting at all times. during the frieza arc, he wears saiyan armor provided by vegeta, but during the cell arc he returns to wearing the orange "gi", accompanied by a blue short-sleeved undershirt and boots. after the defeat of cell, krillin stops shaving his head, and grows his black hair out, before later shaving it again during frieza's resurrection. when he settles down with his family, krillin is shown wearing a workout outfit consisting of a red "tacos" t-shirt and brown drawstring pants.
