I was surprised to find Essie's Yogaga collection at my local Walgreens since I haven't heard about this anywhere. I was looking forward to the Fall 2012 Stylenomics collection, but instead this popped up first. I was able to take a photo of the Yogaga display, but note that there is a bigger display at other stands that includes two additional polishes.

Yogaga: a grayish nude. Almost like a stone color.
Pilates hottie: A creamy pale white with a hint of lavender
