My daughter did this manicure this weekend.
She used wanted a blue manicure and used OPI Dating a Royal. She is young, so is a bit messy applying. Having said that, this is a huge improvement from about a month ago!
..... over the top she put on one coat of Gosh Rainbow.
The flakes on this are amazing. I have wanted to get the NFu Oh version, but can't get it here in the UK. This is very similar. It is also very similar to the Sally Hansen's Hidden Treasure, another shade not available here!
I bought the first bottle of Gosh Rainbow in Superdrug last week, and whilst out shopping today bought another back up bottle!
Thanks for looking.
