I think you might really like these two polishes I picked up this weekend.
First, I got Rimmel Camouflage, in the clearance bucket at Ulta for $1. You may want to check your store for this. It's more frosty than I like but the color and the hint of gold shimmer to this are gorgeous.
Later I was shopping at WalMart for cat litter (yes, WalMart IS evil, and I damn it to hell, but I do get cat litter there) and saw a display of Halloween makeup. For $1 they have mini bottles of polishes, black, orange, I think white, and this little gem below. It has no name or even brand, it's just in black and orange packaging in the makeup section. But wow, what a great color!!
Enjoy if you go find them!!
