S.C. Code Ann. § 24-13-640

Notwithstanding any other provision of law, any state or local prisoner who is not in the highest trusty grade and who is assigned to a work detail outside the confines of any state correctional facility or local detention facility must wear a statewide uniform. The uniform must be of such a design and color as to easily be identified as a prisoner's uniform and stripes must be used in the design. The Department of Corrections Division of Prison Industries must manufacture the statewide uniform and make it available for sale to the local detention facilities. The Director of the Department of Corrections may determine, in his discretion, that the provisions of this section do not apply to certain prisoners.
