My base polish is a little dark to be a true dove blue, but when I googled the color, I saw a lot of pictures darker than I expected, so I guess I'm not too wrong with it. It's Catrice London Calling (Check & Tweed LE), a blue-grey shimmer. I used three coats for opacity and had no issues with application.
For the stamping I used China Glaze Scandalous Shenanigans and Bundle Monster plate BM-S185 (Mystic Woods Set #2). One coat of KBShimmer Clearly On Top finished this mani.
