kardashian kolors was nicole by opi's holiday collection back in 2011. i got a couple of polishes then, but just now got to showing listen to your mom-ager.
i love this polish. it is a royal blue jelly packed with blue, almost foil-like shimmer. even though it is quite old at this point, formula is still spot on. unfortunately, it is a stainer, even though i still get surprised by that when i wear it.
i am sure there are many dupes by now, but i don't have anything like this in my stash (yet!)
i used base (opi start to finish) + two layers of polish + top coat (essence btgnts).
