Intro. Jotaro carries a modified gabardina, in gakuran length/tsume-eri W, with a high and rigid neck, crossed to the left by a golden chain. Below, it carries a sleeveless shirt and tight pants of ¥ 20,000 \[12\], very short and camping, subject by two fine belts, often of different colors, with a pattern of tested triangles of alternate colors (which reflect the headbands of César /José). It also wears leather shoes (presumably) without socks. The iconic Jotaro cap is adorned near the center with a gold button and, on the left, a golden rectangular plate with the design of a flattened hand. He is torn from behind, and seems to merge with his hair.
