How to get this look:
Base Layer: One or two coats of white polish. I used Snow Me White by Sinful Colors Professional.
2nd Layer: Pain spots in any color you like. I chose Secret Admirer by Sinful Colors Professional.
To make the large dots, I dipped the handle of a small makeup brush in the polish and placed the dots on my nails. To make the small dots, I simply repeated this process with a toothpick, varying the amount of polish on the toothpick to get the tiny and medium sized dots.
