I am picky about my nail polish formula. I only use a few brands and the formula, staying power, brush, ease of application, self-leveling, etc. are all important to me. With that said, I own several Essie's because I love everything about their polish. Sometimes it can be hit or miss with buying a polish on-line but this shade surpassed my expectations! Just the right amount of shimmer in it, an absolutely beautiful shade of blue that will work any season of the year, even though it came out in a winter collection. This is one of the few shades where I will probably want a back-up bottle. I love it that much!
