Ready to go over the rainbow? Looks like you are, because this week's most popular pin was a sparkling hue from OPI's Oz: The Great and Powerful collection. We love the When Monkeys Fly shade so much, we can't wait to click our heels and twinkle our tips with a coat of this yellow brick road-inspired metallic. Vote for this polish or any of our lacquer loves, then let us know what else you're obsessing over at by repinning, liking, or commenting on any of our 67 stylish boards—or by clicking the link below.
