Hang on, give me a second to wipe the drool up off my keyboard... Okay, so here is Make Up Store Greta! The most stunning holographic polish to ever grace my nails. I won Greta in a giveaway months ago and never got around to wearing it because it doesn't really look that stunning in the bottle. Boy, am I regretting that! Greta is the standard silver holo, but it's the strongest one I've ever seen.
The awesome thing about Greta (well, one of the many awesome things) is that it ALWAYS looks holographic. It looks crazy good in direct light/sunlight, but is still very holographic in normal household and diffused light. I can't wait to wear this in the summer!
Greta's only downfall was the application. I don't have an aqua base coat for holos, so I endured four (or maybe five, I don't remember) coats of awful dragging and bald spots before it was finally even. I'd be willing to bet that an aqua base would completely fix that problem though. I also didn't use a top coat here because I was afraid it would dull the holo effect.
