After the Rain has a blue shimmer base with multi-coloured glitter - I could see white, red, green, yellow and purple glitter. The base is pretty opaque so it doesn't need undies; this is two coats on its own. It has a great balance of glitter to base and was a breeze to apply.
If We Could Meet By the Sea has small teal and white hex glitter, smaller white glitter and teal bar glitter in a clear base. It's a really pretty combination and it does remind me a bit of the ocean. I've shown a single coat over Essie Turquoise & Caicos - again, it application was very easy. I think this is my favourite of the two!
