I started with three coats of Colors By Llarowe Rockin' My Juju, a midnight blue holo with a subtle shift to purple.
For the stamping I used a England Encore Margot and ÜberChic Geek Love 01 plate. I secured the stamping with one coat of Bundle Monster Smudge Free Top Coat and added one coat of KBShimmer Clearly On Top.
Colors By llarowe are available at their own store, Hypnotic polish, Color4Nails, Harlow & Co and a lot of other retailers.
