The Demon Clothes were originally worn by King Piccolo in the form of an indigo Gi, with a light purple obi with a large kanji 魔 (lit. Demon) on the front and like all Demon Clothes that would follow, Namekian style shoes. King Piccolo wore this outfit from his first battle with Goku up until his death at the hands of Goku during their final battle, though managed to reincarnate himself into his final son Piccolo Junior. In his youth, Piccolo wore a variation of his father's Demon Clothes complete with Demon symbol, though with purple sleeves and no belt. It is later revealed through Kami's flashbacks that King Piccolo's Demon Clothes was actually inversion of the young Kami's Namekian Gi, with the Demon symbol in place of Kami's 神 (Kami lit. "God").
As a teenager, Piccolo switched to his own unique set of Demon Clothes a dark purplish blue gi with a sky blue obi (red in the manga) and lack the Demon symbol entirely. When not fighting seriously, Piccolo also wears a white turban with a dark purplish blue color on top same as his gi and a white cape with built in shoulder padding along with it. After his defeat at the hands of Goku at the 23rd World Martial Arts Tournament, Piccolo added weights to his turban and cape which he continued to wear for the rest of the series when not fighting seriously.
During the Saiyan conflict near the end of his training with Gohan, Gohan had switched from his Turtle School Gi (Demon) to his own set of Demon Clothes, consisting of a dark purplish gi, red obi, white scarf, and white bandana. This set was later destroyed when he transformed into Great Ape during the battle with Vegeta, though he secretly made himself another nearly identical set, though without the bandana which he later changed into after leaving the Earth on the Nameless Namek's spaceship.
Gohan continued to wear it until he switched to the Battle Armor he obtained from Vegeta on Frieza's Spaceship which he wore throughout the following Frieza Saga and wore during Trunks Saga. During the Androids saga, Gohan once again returned to his Demon Clothes which he wore until he switched to the Battle Armor developed by Bulma. After completing his training in the Hyperbolic Time Chamber, Gohan asked Piccolo to make him a new set of clothes like Piccolo's, so Piccolo created a set identical to his complete with cape, minus the turban. Gohan later removed the cape during his battle with Cell, though continued to wear the rest of his outfit for the duration of the Cell Games and its aftermath.
In Dragon Ball Z: The World's Strongest, Gohan wore a long cape though different in style from Piccolo's with his early Demon Clothes set when searching for the Dragon Balls with Oolong at the beginning of the film and when he came to aid his father against Dr. Wheelo. Gohan also his original style Demon Clothes set in the films Dragon Ball Z: Cooler's Revenge, Dragon Ball Z: The Return of Cooler, and Broly - The Legendary Super Saiyan.
In Dragon Ball Z: Broly - Second Coming, Krillin humorously wore a set of Demon Clothes identical to the one worn by Piccolo complete with cape and turban, which caused Gohan to hallucinate Krillin was Piccolo when he saved him from being killed by the lava he had tried to use to defeat Broly who survived and knocked Krillin out with one punch. While most of the outfit fit him, the cape was too long for someone of his height.
In Dragon Ball Z: Resurrection ‘F’, Piccolo used the weights in his turban and cape against one of the Combatants he was fighting causing the soldier who was using flight at the time to fall to the ground due to being unaware that it was weighted and confused as to why Piccolo was throwing it to him. This usage proved to be an effective and useful method of removing both the weights allowing him to fight unhindered and taking out one of his opponents at the same time, serving as another example of Piccolo's tactical genius.
