Three coats, with top coat (forgot which one :P)
Did this mani shortly after I got the ruined package from Ulta. I filed my nails a bit, so they're a little shorter and rounded.
No undies for this, didn't need it. Probably could've gotten away with two coats. This surprised me, I didn't think I would like it very much. Formula is good, no horrible streaking or dragging, nor is it too thick.
