The most distinctive feature on his suit are the three ladybug emblems located on either side of his chest and directly below his zipper, matching the appearance of his stand. Later on, his shoes also have the same ladybug emblem on them. The color scheme for his suit is blue outlined with gold.
His overvall appearence resembles his father's, having the same height and weight as him. Giorno has a small star-shaped birthmark on the rear of his left shoulder, close to his neck.
After becoming Passione's boss, Giorno decided to find information about his father. With some searching, he found out that the star on his shoulder is the Joestar Birthmark, so after travelling to the US, Giorno met an old Joseph Joestar, who told him he had an adventure which had something to do with DIO, but now being senile, Joseph doesn't remember most of the adventure.
After returning to Italy, he revealed to Polnareff that he is DIO's son, so Polnareff told him the story Joseph talked about; after that, Giorno decided to write a book about his family.
Travelling to England, he found the old documents with Dio Brando's information, in which Dio's birthday was listed as 4 July, 1868 and his death as February 7, 1889. Giorno was confused about his father being over 130 years old, after that, he begged to the Speedwagon Foundation to told him about the truth of his father. The Speedwagon Foundation told him about the stone mask and the vampires, and after some blood test, Giorno found he is 1/4 vampire.

Now trying to found more about Jotaro, he discovered that Jotaro has a daughter called Jolyne living in Florida. Giorno told Mista to find Jolyne so he can have the last part of the story to fulfil his family record.
