Mermaid by Piggy Polish is a lovely opalescent green/teal shade. It is very sheer, I'm wearing 3 coats to get some opacity with Essie Millionails as a base and OPI Top Coat on top. There is still a visible nail line as you can see in the photos.
You could almost call this color a duo chrome with how it shimmers like a Mermaid's tail when the light hits it. Sometimes it's invisible, other times it flashes blue and green. I had difficulty capturing the depth of color in this shade.
Trust me you'll be staring at your nails a lot while wearing this shade. And who knows maybe on your toes it could magically bring you a lovely matching tail at the beach. Whatever will that cute lifeguard do?
Feeling like channeling your inner mermaid?
