This is Borghese Palermo Plum, Sally Hansen Xtreme Wear White Out, Zoya Dree, and Sally Hansen Insta-Dri Lightening.
Palermo Plum is still one of my favorite polishes. The application isn't great - it's a little thin and runny, so flooding is an issue - but the color is just so rich and beautiful. There's a bit more blue to it than what shows in these photos.
As far as design, this didn't turn out quite like I had hoped, but it's still pretty cute.
