Here's what I used"
L.A. Colors Art Deco in a hot pink colour (dots)
Sally Hansen HARD as NAILS Xtreme Wear polish in White on (dots)
Sally Hansen HARD as NAILS Xtreme Wear polish in Sand Dollar (as main colour)
Now, I'm not sure about all of you out there but for me, I always find it hard to make perfect dots with just the polish brush alone. So, instead of using the brush I used.....a bobby pin! I just opened a bobby pin and dipped the end of the bobby pin into the polish onto my nails. It gives the perfect polka dot with the perfect size as well. Try it out and let me know how it goes! Ta-ta for now!
