Today I've got a look at Black Tie Event by Polish Addict. It's a multi-colored glitter in a black gel base. I had to layer several coats to get it to this opaque look. You could layer it over a black and only use 1-2 coats but then you won't have the depth from all the layers of glitter. This polish is so fun and festive and there wasn't anything I did not like about it.
