Showgirl Chic has a silver glitter base, with larger blue glitter pieces throughout. It's absolutely gorgeous.
The glitter is really dense in these polishes, which is awesome. You do have to shake the bottle quite a bit though to get it all mixed up again if it has been sitting for a while. I didn't shake mine enough, so if I didn't dip the brush in the polish deep enough, I got very thin coats with almost no glitter. If you do shake it up enough, though, you'll be rewarded with glittery goodness, almost as dense as a foil. Two to three coats of Showgirl Chic will turn it opaque, depending on the thickness when you apply it.
A warning: This polish might temporarily blind you. If you catch rays of sun at just the right angle, it'll bounce off like from a disco ball. I think Showgirl Chic has claimed three victims so far.
Here's Sally Hansen Gem Crush in Showgirl Chic, three coats, over a coat of Seche and topped with a coat of Seche as well.
