Goku

Due to his love of training, he is most commonly seen wearing a Gi. Originally, Goku wore a blue gi secured with a white bow-tied obi over his waist, red wristbands, and dark blue kung fu shoes. He later wore a white tank top while training under Master Roshi. Following this, Goku wore the basic Turtle School Uniform, consisting of a red (later orange) gi secured by a black knot-tied obi over his waist, blue wristbands, and blue kung fu shoes. On the left chest and back there is a yellow patch with Roshi's kanji. After training with Kami and Mr. Popo, Goku wore a black short-sleeved undershirt (later dark blue) with this gi and replaced his shoes with dark blue boots with a yellow border and red laces. In Dragon Ball Z, the patches containing the Turtle School kanji became white. After training under King Kai, Goku wore King Kai's kanji on the back of his top. During the Frieza Saga, Goku wore his own kanji on both sides of his top. During the Cell and Buu Sagas, Goku wore a plainer version of this gi that lacked any kanji and featured a blue sash-style obi over his waist, as well as the same dark blue undershirt, same wristbands and the same boots from his previous gi, but with a red border and yellow/tan laces. He later retains this outfit throughout most of Dragon Ball Super, while also regaining his own kanji on both sides of his gi shirt.
