Ooh pretty! Sephora by Opi nail polish in a delightful shade of blue called "Slushied" from their Glee collection. Got one for free from the Vogue Influencer Network and love it! It's part of the "Sephora Hot Now" assortment for March.
I can't stand nail polish on my fingers, but "Slushied" definitely looks awesome on my toes (the cat thinks so too), and it stays on forever!
