I just re-swatched this polish (one of my favourite indie polishes), Pahlish Toxic and Timeless. This is actually the third bottle of this polish I've tried. This is one of the older formulations (though from what I can tell, it's not the original version). The base colour is very clear and jelly, but takes a few coats to wear on its own (see solveig's amazing swatch here).
I used 3 coats over 2 coats of NARS Midnight Express for the pictures below. In real life, I prefer just 1 coat of the NARS as undies, because you get more of a jelly finish (but since I take pics with flash, it would have photographed terribly). I believe Shannon's reformulated this shade to be opaque in 2 coats now based on customer feedback, but I think I like this version the best ♥
