I like layering whether it is shimmers, glitters, flakies or anything else. Whenever I swatch a polish I always do second set of pictures after applying some layering polish or doing nail art on it. This is one of the cases. I've swatched Dr.'s remedy DEFENSE Deep Red polish and then added one layer of CND Crimson Sparkle.
I like the duochrome and sparkle effect of Crimson Sparkle, it creates unique look every time.
