See those two polishes above? I'm not sure when I even got these, they're both years old (and remarkably still in good shape! Just needed a good shake each!), but both layered over Color Club "Disco Dress" made one of my favorite combinations ever.
I have a thing for purple and green combinations, and the three of these made this AMAZING purple with an awesome green, sparkly, iridescent sheen to it. I couldn't even capture it on camera correctly.
So, sadly, there won't be any photos of the results just yet (not until I do this again, at least), but if you happen to have any of these colors laying about, TRY IT.
Colors used; Color Club "Disco Dress", Sally Hansen Nail Prisms "Turquoise Opal", and Liquid Euphoria...color name unknown. It's purple with a great green sparkle to it.
