My base is Essie Pool Side Service, a slightly muted teal creme. I used two coats for opacity and had no issues with application.
Then I added one coat of Essie Shine Of The Times, a clear based flakie topper with flakies shifting from green over gold to a red-ish pink. One coat of KBShimmer Clearly On Top gave some extra shine.
Since I love matted flakies so much, I then applied one coat of Picture Polish G'Day Matte.
