Beautiful blue polish! From their Fall 2016 Collection, Essie's Udon Know me is an antiqued, slightly dusty shade of sky blue. Sort of like a blue version of Zoya's Wednesday. I have a lot of blues in my collection but none that look quite like this one. Very flattering on the nail.It's in the same family of blue as Butter London's Victoriana (but I like this Essie more) and has an excellent formula. Opaque in two coats and no problems with application or wear.I'd definitely buy this one again. Recommended!
