Essie Topless & Barefoot is probably the most nude polish I own. It's a tad lighter than my skin-tone, which makes it semi-wearable. I am sure there are people out there that wouldn't like this look, but I do. It's a very clean look.
The Essie Spring 2011 Collection - French Affair was one of my favorite collections. I have Topless & Barefoot, French Affair, and Sand Tropez. These are all such beautiful pale/light polishes.
