I'm on the back half of the cuccio Fall/Winter 2022 Speakeasy collection and this is Hotsy Totsy, a violet duochrome. This was a very thin polish that did build up.
I started with Morgan Taylor REACTmax in Optical Brightener, three coats of polish, and finished with Zoya Glossy Seal. As I mentioned, it was very thin but did build up.
