Mo. Rev. Stat. § 630.225

Before any patient who can support himself is admitted into any facility operated by the department, he shall be furnished, by those responsible for his support, with suitable changes of clothing. If patients who are able to support themselves as determined under section 630.210 are in need of clothing, the business manager, under the direction of the head of the facility, shall furnish the same. The department shall calculate expenditures for such clothing as part of the per diem expense. Nothing in this section shall be construed as prohibiting the purchase of clothing by, or gifts of clothing to, a patient or resident by his family or friends.
