Deborah Lippmann's polish. It's the one of the brands I don't mind paying full price for a bottle - well I sort of don't mind. The other is Nars and RBL. I do try and wait for a sale and when Beautysak had one recently I pulled the trigger on a few polishes from Deborah Lippmann. Waking Up In Vegas was one of them.
It's so creamy and smooth and practically applies itself. It does dry to a satin type finish but a topcoat gives it shine. Oddly enough I don't have a dupe for it. I thought I did but the closest I found was American Apparel Mouse and that is darker. Everything else I pulled out was too dark, too light, too purple, too grey - you get the point. I do love these grungy colors.
My topcoat is giving me issues so don't mind the not so even finish.
