I used two coats of OPI's Ski Teal We Drop and one coat of Nubar's 2010 top coat which is a gorgeous flakie. I love this combination, the flakie stands out so well against the deep teal polish.
As you can see I have used lots of the Nubar top coat polish, I wear it so much and I find it jazzes up any dark polish. Of course you can wear it on top of any polish but I prefer wearing it over a dark base, the flakies pop more.
OPI polish on its own:
I really want to try the Finger Paint flakies, shame we don't get that brand in the UK,
