There is no national law prohibiting nudism, but Pennsylvania law Title 18 Section 3127 states that "a person commits indecent exposure if that person exposes his or her genitals in any public place or in any place where there are present to other persons under circumstances in which he or she knows or should know that this conduct is likely to offend, affront or alarm." Nudity in Pennsylvania is generally prosecuted as a misdemeanor, largely dependent upon the public nature of the offense and on the age of other individuals present. Basically, nudism or naturism in Pennsylvania is best practiced on private property or in wilderness locations - away from the public eye.
