I have quite a beauty for you tonight! Milani Totally Cool is quite aptly named because it IS totally cool. It is a gorgeous "blurple" (blue/purple) but in certain lighting it is a straight dark purple. The most amazing part of this is the shimmer that seems to have a duochrome quality to it that shifts from pink to gold depending on the light.
The only complaint I have about this polish is that it is sheer. I had 3 coats and it was OKAY but I could still see slight VNL. I added one more coat and was happy with it. What you are seeing in the pics is 4 coats, no top coat.
I have taken some pics outside and some inside so you can see the difference in the color and shifts.
This color is from 2009 and is somewhat hard to find in stores but can be found (right now) at milanicosmetics.com.
