Chapter 2: Jotaro Apparence
Jotaro is canonically established as a tall (195 cm/6'5"), attractive, and well-built man, even as a teenager. He has dark hair that constantly blends with his hat, a strong jaw, bold eyebrows, and green eyes. He also bears a mild resemblance to his great-great-grandfather, Jonathan Joestar, and his grandfather, Joseph Joestar when he was young.
The superficial theme of Jotaro's attire changes in each part. His trademarks are a visored, ornamented cap, torn at the back and blending with his hair, and a roughly mid-calf-length coat with a standing collar and chains attached. His attire was influenced by Babel IIW, a famous manga of a boy in a gakuran having an adventure in a desert.
Jotaro wears a modified trenchcoat-length gakuran/tsume-eriW with a tall, stiff collar, pierced on the left with a golden chain. Underneath, he wears a fitted, sleeveless shirt and a pair of slim-fitting ¥20,000[11] pants of very short, sharp flares held up by two thin belts, often differently colored, patterned in a row of alternately colored tessellated triangles (reflecting Caesar/Joseph's headband). He also wears a pair of leather shoes (presumably) without socks.
Jotaro's iconic cap is adorned near the center with a golden button and, on its left, a rectangular golden plate with a design of a flattened hand. It is torn at the back, appearing to merge with his hair. While they are first shown as being completely separate but slightly torn, later publications cause more uncertainty as to where his hat and his hair actually meet. According to Araki in an interview, he wanted readers to recognize Jotaro even from his back, and not just his forefront.[12]

Jotaro again wears a dark overcoat; this time of more detail. Lines ring the top and the base of his collar; joining to run the length of the coat's opening. The surface of his collar bears two star pins, with one on the inside, along with a small chain piercing the left. Two lines run the top of the shoulders, with two more radiating from his collar to their sides. Two zips lie between the chest and the stomach. The sides of the shoulders bear large stars, beginning a light stripe reaching his cuffs (also bearing a star) that reads "JOJO", repeatedly. A line runs from the armpit to the end of the coat.
He wears a light under-shirt, printed at the chest with a large star. His shoes and pants are of a piece in a snakeskin texture. He wears a single leather belt, studded in two rows, folded behind itself after the buckle.
