The terms "PVC", "vinyl" and "PU" tend to be used interchangeably by retailers for clothing made from shiny plastic-coated fabrics. These fabrics usually consist of a backing woven from polyester fibers with a surface coating of shiny plastic. The plastic layer itself is typically a blend of PVC and polyurethane (PU), with 100% PVC producing a stiff fabric with a glossy shine and 100% PU producing a stretchy fabric with a silky shine. A manufacturer's label may say, for example, 67% polyester, 33% polyurethane for a fabric that contains no PVC; or 80% polyvinyl chloride, 20% polyurethane with mention of the polyester backing omitted. To add to the confusion, the plastic layer is often textured to look like Leather, ("leatherlook", "pleather"), as opposed to smooth.
