I tried doing the same thing with Currant (I don't have Nightmoth), but that doesn't fully fix the problem. I played with Instigator awhile this morning, and it's going back. Maybe I got a bad batch or something, because the one I swatched on my hand at the store wasn't like this in the least.
Even with P&P, the application is patchy. That isn't true of any other lipstick I own. This is about as friendly as my palette Cyber, meaning not at all. If I apply it more heavily, it's still not even. I don't mind using P&P and liner to make a lippy work; I do that anyway. But when it settles into lines I don't normally see even over primer it's going back. I wouldn't even sell this to anyone. It's a dud.
Studded Kiss, on the other hand, applies divinely.
