Toms Shoes had a sweepstakes to win a free bottle of Essie polish for their "One Day Without Shoes" event. Essie One Day Without Blues is a special color made especially for the collaboration. It's a dusty cornflower blue cream with subtle silvery shimmer. The formula was very easy to work with, and was almost opaque after just one coat. It is a very pretty color, but not particularly unique. I think it is similar to Zoya Jo, but I have no swatched these next to each other. I am grateful to add this Essie to my collection.
