I got this Wet n' Wild Fast Dry Nail Color in Gray's Anatomy (P199) a few months ago at Watsons. I tried it once, but I didn't like how it was so sheer that even three layers weren't enough! This time though I decided to use an opaque base just to make the duochrome effect pop out. I'm glad to report that it worked. :D
This duochrome effect is very similar to Chanel's Peridot polish at only a fraction of the price. Don't be fooled by the bottle though, the effect is not as pronounced when worn. You'll see it only at certain angles.
I also adore this Bobbie shade called Parasail. Are you seeing that blue shimmer? Subtle yet stunning. Not bad for P36!
