Wishful Thinking is a holographic top coat... Wear it over any of your favorite polishes, or wear 2-3 coats for a silvery holographic look. Wishful Thinking is shown with 3 coats on its own, and as a top coat over SUPER BLACK Hello Officer, SUPER BLACK Murdered Out, and SUPER BLACK Grassy Knoll. We recommend you skip the top coat over this polish, because the holographic effect works best with nothing over it!!
