I got the brilliant idea to wear a holo polish, but I didn't realize it wouldn't be so sunny today, lol. So here's an older mani :)
This was 3 coats of China Glaze Tantalize Me. That polish has a lovely blue glow so I figured Nfu.Oh #50 would match nice with it, I think I used 2 coats of that. But -how to explain this- the flakies on a lighter color show the actual color of the plastic a bit better in some light, a bit light brown or some, and I don't think that looks so nice. So I added a coat of Essie Matte About You, and that helped a bit :) The shimmer in Tantalize Me isn't so visible anymore, but it seemed to make the flakie color pop out even more.
