Papa Jotaro

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. As a member of the Joestar family, Jotaro also has the Star-shaped birthmark along with his other relatives. In Diamond is Unbreakable, Jotaro looks noticeably paler and a little more slender, and wears mostly white instead of all black. Over the course of the fourth part, Jotaro has three outfits:

His first outfit consists of a white trench coat with a matching belt draping diagonally in front of a bluish-purple sweater, which somewhat matches his shoes. Underneath his sweater, he wears a light green shirt with a flared-out collar. Similar to his appearance in Stardust Crusaders, he wears two belts, which are decorated with triangles that alternate colors. The ends of each of his sleeves also have triangles on them. He wears a white hat, the front of which displays a golden "J" next to a heart that contains an open palm inside, and the circumference is also golden. He wears his second outfit during the fight against Bug-Eaten. He wears another white coat, whose sleeves are now pink, but they're white in the manga. Two pins are secured near his collarbones: one of two dolphins kissing, forming a heart, and one of a sharp triangle that has his signature palm inside. His hat is still white and gold, but the pins on the front are even more detailed; the "J" now resembles a dolphin and the heart has been replaced with a sun with an Aztec-looking face inside. His two belts are now dark blue, and he wears a dark pink shirt, which is white in the manga, under another white belt. His shoes have laces and go up a little higher than they did before. His third and final outfit bears a very slight resemblance to his Part 3 outfit, though the differences are still significant. The front of his hat now has three "anchors" that resemble Prince's "Love Symbol", followed by his famous palm sign. Under his coat, he wears a black turtleneck with another palm sign on the center of his neck, and a purple belt drapes in front of it. A thin, light blue undercoat with dark gray patterns resembling more "Love Symbols" can be seen under his white trench coat, which has the same sleeves as his first Part 4 outfit. His two belts are now blackIn Diamond is Unbreakable, Jotaro becomes notably more mellow and mature with age, forming a friendship with the young Koichi Hirose and taking Josuke Higashikata under his wing while expressing interest in Koichi Hirose's abilities, though he still has moments reminiscent of his younger self, such as yelling at Josuke's groupies during their fight. While still largely stoic he has given up smoking and drinking, and is more openly polite in the presence of other than before and still isn't afraid to get involved in deadly battles and put his life on the line.
