I started with 3 coats of Revlon - Blue Lagoon. A pale blue with a silver/blue/purple shimmer which is pretty but never shows up on camera. It has a weird finish, not shiny, not matte, not really satin matte, kind of matte-shiny but more matteish? Ok I topped my worst description ever, but basically it's not your standard creme.
I added one coat of Models Own - Indian Ocean, I like it more as I use it more. It's a shimmery blue/purple duochrome, it makes blues pretty (unless they're dark, then a weird shade of purple shimmer turns up and it's not as nice).
Finally I used 3 coats of OPI - Last Friday Night, a sheer blue base with iridescent glitter and a blue micro-shimmer thing which is gorgeous. Looks awesome over light purple too, it's a lovely subtle glitter to complete the combination. I love me some blue nails anyway.
Thank you for reading and I hope you have a lovely weekend!!! :)
