Here's the polish I used... Start with Essie "First Base" base coat. Follow with two coats of Essie "Sand Tropez." Follow with polka-dots in OPI "Alpine Snow." Finish with your favorite top coat (I use CND "Super Glossy"). If you haven't tried drying drops, yet - go get some! I used Essie drying drops, but OPI also makes a similar product. One drop on each nail after polishing dries nails in about 5 minutes... perfect for people like me that can't sit still long enough to allow their manicure to dry completely.
I used a small dot painting tool to create the polka-dots. You can get one at a beauty supply store or even a craft store. But you could also use a toothpick.
Start out with just a few polka dots at the tips of your nails. Then gradually add more to about half-way down your nail. Add the most near the tip, and only a few small dots as you move toward the middle of your nail.
Try it with any color combination you like! Have fun!!
