Portal:United States Copyright Office, US Copyright Office Policy Decision on Registrability of Costume designs… (1991)
“ For purposes of copyright registration, fanciful costumes will be treated as useful articles. Costumes serve a dual purpose of clothing the body and portraying their appearance. Since clothing the body serves as a useful function, costumes fall within the literal defintion of useful article. In addition, the case law consistently treats costumes as useful articles, and a Copyright Office decision to differ substantially from these court decisions would appear difficult to justify. ”
