Wearable art, also known as Artwear or "art to wear", refers to individually designed pieces of (usually) handmade clothing or jewellery created as fine or expressive art. While the making of any article of clothing or other wearable object typically involves aesthetic considerations, the term "wearable art" implies that the work is intended to be accepted as a serious and unique artistic creation or statement. Pieces may be sold and/or exhibited. The modern idea of wearable art seems to have surfaced more than once in various forms. Marbeth Schon's book on modernist jewellery (see the section on jewellery below) refers to a "wearable art movement" spanning roughly the years 1930 to 1960. A 2003 "The New York Times" review of a book on knitting refers to "the 60s Art to Wear movement".
