Today seems like the perfect time to post this polish from CrowsToes; it's called Making Christmas and is chock full of red and green and holo glitter. I used three coats plus topcoat for these swatches. If I'd thought to put a base color on first—dark green or wine perhaps—I could have used one or two coats. As it is, I got serious bling as the glitter piled on glitter.
In lower light, the holo glitter goes nuts and sparks off all sorts of colors.
I love super sparkly polishes like this. I could definitely see wearing it as a full mani for a party; for work, I'd probably use it as an accent nail.
