The only thing I love more than a holo is a good duochrome. I'd never even heard of this polish before, but I recently acquired it through a great multiswap through MakeupAlley.com. This polish has been around for awhile and is still relatively easy to find online. The colors in It's Up to You are absolutely captivating. This polish has a blue base, bright but not super bright, that flashes with an aqua blue glow in bright light, and in the shade there is more of a turquoise flash. Then on the very edges you can find a hint of indigo blending to purple. Oohhhh, love so much. Enjoy!
