Hello! I used to be fairly fickle when it comes to my white "go-to" polish, however this has been a firm favourite for a couple of years now. I go through so much white as I pretty much start all nail art with a white base, I need a polish that's opaque in 1-2 coats, and dries quickly - and this is just the ticket.
My previous favourite used to be Sinful Colors, but that's pretty much impossible to get hold of in the UK now. Rimmel White Hot Love is easy to get hold of (they even sell it in the supermarket so this is great for me.
