Sinful Colors Beverly Hills (purple/pink)
Sinful Colors Cool Grey (actually, the bottle I have is nameless, but after doing some research I’m pretty sure that’s the color)
I bought both of these polishes recently at a local dollar store. Cool Grey is two coats, and so is Beverly Hills, though you could get away with just one. For the half moons, I used paper reinforcement stickers; they give a really clean line, though for this design it’s not too important, since the pearls cover it.
