natural light, 2 coats
The formulation was really easy to work with as well, except I wasn't happy about how it dried. This polish dries to a semi-matte finish, meaning if you don't use a top coat, it is going to be very flat. However, even after applying TWO coats of my glossiest top coat, it still had a very flat appearance (see above). I swear this polish is a magical top coat sponge, because the top coat just disappeared within minutes. I like my nails glossy enough to see my reflection in them, so this was a definite con for me.
As far as dupes go, the closest one I can think of is the OPI Katy Perry "The One That Got Away", however they are a bit different. TOTGA (ha! love that acronym) is more red/pink, and the microshimmer is even more micro.
If you love the color and don't care about glossiness, you would probably really like this polish. If you are a stickler about glossy nails, this isn't for you (especially with its $18 price tag).
Do you care if your nails are glossy or not?
