A prison uniform is a set of standardized clothing worn by prisoners. It usually includes visually distinct clothes worn to indicate the wearer is a prisoner, in clear distinction from civil clothing. Prison uniforms are intended to make prisoners instantly identifiable, limit risks through concealed objects and prevent injuries through undesignated clothing objects. A prison uniform can also spoil attempts of escape, as prison uniforms typically use a design and color scheme that is easily noticed and identified even at a greater distance. Wearing a prison uniform is typically done only reluctantly and is often perceived as stigmatizing, and as an invasion into the autonomy of decision. The Standard Minimum Rules for the Treatment of Prisoners first adopted in 1955 and amended in 2015 as "Mandela Rules" prohibit degrading or humiliating clothing, requiring in Rule 19 that: Every prisoner who is not allowed to wear his or her own clothing shall be provided with an outfit of clothing suitable for the climate and adequate to keep him or her good health. Such clothing shall in no manner be degrading or humiliating. All clothing shall be clean and kept in proper condition. Underclothing shall be changed and washed as often as necessary for the maintenance of hygiene. In exceptional circumstances, whenever a prisoner is removed outside the prison for an authorized purpose, he or she shall be allowed to wear his or her own clothing or other inconspicuous clothing.
