Here’s Mumbling by Kae aka The Hungry Asian. This is described as a silver and gold holo glitter (in a sheer base), and it looks great already in the bottle (by the way, I love the heart-shaped bottle, it’s so cute 🙂 ).
On its own, two coats.
One coat over OPI Cosmo-not Tonight, Honey (would look awesome over black too, I guess).
Kae has got an Etsy shop now, you should check this out! 🙂
