I purchased Deviantly Darling based on what it looked like in the bottle - teal that shifts to dark blue. Unfortunately, I did not see that transformation on my nail! I really really wanted to like this one, but ultimately felt let down by it.
I must say, so far in the see of duochromes we are seeing, I am still loving the Nicole by OPI 2012 Target exclusives (Mer-maid for Each other and Iris My Case) the best!
Which duochromes have you had the most success with?
