The materials of the Harley Quinn cosplay costumes are Shiny spandex wet look spandex , lycra spandex, or pvc.
We've managed to find a few more cosplays that show off the range of Harley's different looks as well as the ingenuity of her fans! Everything is made from latex and rubber to fit the head of the wearer, and then painted with a variety of acrylic paints.
