I love sparkly nails. Everytime I see a sparkly or glitter nail polish I have to but it. I have found that some don't turn out as good as others, they look like you haven't put enough on. This is why I tend to put a similar colour as a base.
What I used
Y.C.C nail enamel 110

I used one coat of the Collecton 2000 and two coats of the YCC to give it a very blue and glittery effect.
