Once Upon a Time is one of three Whimsical polishes I own. I featured Wicked a while back and still have one more to try out. Once Upon a Time has a clear base with lilac and mint green glitter. I had a bit of a tough time deciding what to layer it over before finally deciding on Revlon Hazy a pale gray creme. I think this combo looks lovely together! I can't wait to try this one layered over some other colors as well!
