Abstract: The differentiation of product clothing and art clothing enriches the value connotation of clothing, that is, product clothing more prominent its economic value carrier function, while art clothing more prominent its cultural value carrier function. As the carrier of cultural value, the key of art-style clothing lies in innovation, and the protection of innovation can promote the development of art-style clothing, and further promote the spread and development of clothing culture. General secretary Xi Jinping has pointed out that "protecting intellectual property rights is protecting innovation". Copyright law is an important system to protect and promote cultural innovation in intellectual property system. In terms of art-type clothing, the legal status of the object of copyright should be affirmed, the identification standard of the object of copyright should be refined, and the protection of copyright law should be given on this basis.
