Why did Mary wear a red dress at her execution?

Mary, Queen of Scots, wore a red dress at her execution on February 8, 1587, to symbolize her Catholic martyrdom. The color red represented her belief in her royal status and her willingness to die for her faith. Additionally, it served as a statement against her execution, projecting dignity and defiance in the face of her fate. Her choice of attire was meant to convey strength and resolve during her final moments.
