I know this comparison has probably been done to death... but I had to see it for myself. OPI My Private Jet is one of my all time favourite colours. When it first came out I just could not get enough of the colour..... now it seems that OPI have changed the formula and ... I am sad to say I no longer like MPJ. I find the newer version to be less of a holo, have a somewhat purple base and applies like crap... far too thick. So I guess I will have to cherish the only bottle of OLD formula MPJ I have....... boo on you OPI!
