Jazz is discontinued but I brought it off an etailer, so its not really HTF yet :D
This was three coats. It applied really nicely which surprised me, as all the Essies I have tried have been crap. Although I haven't tried many...
I really like Jazz as it suits my olive skintone nicely. I am not that excited about it as I was over Let Them Eat Rice Cake, but it is a very 'appropriate' shade.
I tried some marbling with Jazz as the base... didn't turn out too well D: I will try again tomorrow though!
