This is OPI's Malibu Blue, from the California collection only released in Australia quite a little while ago. Same collection from Earthquake!, Tahoe Topaz and Beverly Hills Chills.
I used three coats here. It seemed very watery and that's a nightmare without the pro-wide brush... It means a lot more polish needs to be applied for one coat to make it even and opaque.
Malibu Blue is a denim blue frost with scattered silver flecks, making it very very shiny in the sunlight!
When I received Malibu Blue, I thought it looked very similar to Blue Jeans... and it is. On the comparison shot at the end of the post, Pick Me Up Purple is on the index, Malibu Blue on the middle and Blue Jeans on the ring finger. Only a slight difference eh? Bye bye Malibu Blue.
