2 coats China Glaze Up All Night
1 coat Poshe
1 coat Twilight
Twilight is an interesting TOP COAT. Yes, it is a top coat. I saw a couple of reviews on MUA rating this polish low because I don't think they realized it was meant to be a top coat. But as a top coat, it's actually very pretty.
The formula was fine. It's a top coat, hard to screw that up when it's something simple like this. It did not smear my polish underneath. You could use a light touch and get just a little shimmer, or go over it a few times (which is what I did) to pull out a lot of shimmer.
