I've had this on for four days now, and oddly, it seems like longer. This is four thin coats of OPI The World is Not Enough.
I used Sephora X base coat under it and Sephora X top coat over top. For whatever reason, the X base and top combined with OPI has been giving me better than normal wear! Hooray!
It's still not as good as my nine days with X polish...but four or five days with OPI is novel and fun for me!
I tried to wear this one earlier and had some icky bubbling, likely because I went too fast. I say "too fast," but really it was as fast as I normally go (not waiting between coats or anything). This type of polish, I find, really needs some patience and babying. What should I even call this finish? Metallic shimmer?! It's freaking gorgeous, whatever it is.
So, yeah, just GO SLOW, and it will all be okay and be totally worth it. I waited between my coats, I made sure to do thinner coats than normal (thus the need for four coats), and presto-magic-o, my mani was near perfect!
Also, just so you know, this is way prettier in person than in pictures. It's super shiny and metallic looking. In some lights it appears a bit purple to me, which I really enjoy.
