The seven knights of the Kingsguard took the field, all but Jaime Lannister in scaledĪrmor the color of milk, their cloaks as white as freshfallen snow. From his shoulders hung the pure white cloak of His helm, Sansa saw that he was an old man with hair as pale as his armor, yet he Snow, with silver chasings and clasps that glittered in the sun. One knight wore an intricate suit of white enameled scales, brilliant as a field of newfallen Queen, in armor so fine and gorgeous that it made her blink. When she got closer, she saw two knights kneeling before the Jaime wore the white cloak of the Kingsguard over his golden armor.
The general description of the Kingsguard's equipment seems to be: a long white cloak and white armour, usually with enamelled scales. In HBO's Game of Thrones TV Show, the depiction of the Kingsguard has had various, minor changes throughout the show, but was always relatively consistent and faithful to the books, up until Season 7.
