Nakedness and dress in Shakespeare's King Lear, represented the status of a character. Many scenes use clothing to show one characters dominance over another. The more opulent the clothing, the higher the status, or the lack of clothing, the lower the status. A few characters go through many wardrobes.

Edgar, legitimate son to the Earl of Gloucester, is well dressed, not as much as Lear, but still above commoners. Edgar is believed to be plotting to annihilate his own father.
