I used two coats of Pee Wee Purple. On my accent nail, I topped off Pee Wee Purple with two coats of Mermaid Magic. The swatch on the nail wheel is what two coats of Mermaid Magic looks like by itself. The formula on these polishes were great and gave me no problems. You probably could wear Mermaid Magic on its own but I tend to layer glitters that don't have complete coverage. I have really been loving all the Hard Candy polishes so far.
