It is unlawful for any person to employ a person under the age of eighteen years to appear in a state of sexually explicit nudity, as defined in Section 16-15-375(6), in a public place.
Mistake of age is not a defense to a prosecution under this section. A person who violates this section is guilty of a felony and, upon conviction, must be imprisoned not more than five years or fined not more than five thousand dollars, or both.
