Finally at the last polish in the cuccio Fall/Winter 2022 Speakeasy collection and this is Giggle Water, a blue/grey duochrome metallic. This is a color you've seen before by several different brands.
I started with Morgan Taylor REACTmax in Optical Brightener, two coats of polish, and finished with Zoya Glossy Seal. I was pretty surprised and happy that it only took 2 coats for this one.
