from the Bohemian Brights mini set
Ok, I've totally solved The Mystery of the Sephora by OPI Minis. My set was definitely switched around (probably by a cute little 6 year old who resides in my house). And this shade is definitely Let's Hear It For the Free Spirit!
The above swatch is two coats, and I was pleasantly surprised that it covered this well.
And now I am officially ready for Spring! Isn't this pretty?
