What doesn’t count as visual art? Clothing? Or does haute couture count as visual art? 

Section 8 of the Act defines what is a visual artwork, and does not refer to clothing – although it does refer to drawings and textiles, so while the clothing items themselves may not be regarded as an original visual artwork,  the underlying drawings that they are based may be regarded as an original visual artwork, and the same with the textile designs.  Arguably if the clothing item is at the level of a WOW entry, it might be regarded as sculpture and therefore would be included in the definition of an original visual artwork.
