Joseph has a muscular build fit with marine blue eyes and brown unkempt hair. He usually wears a tank top cut above the navel, fingerless gloves, fitting pants with a leather belt, and high-knee leather boots. Joseph also wears a striped scarf that was a posthumous gift from his friend Ceaser. Joseph, like all Joestars, has a 5-pointed star-shaped birthmark on the back of his left shoulder. After his left hand was cut off by Kars, it was replaced by a prosthetic that can mimic hand movements.
