Midnight Cami is a very popular Essie polish but I just don't love it. The colour itself is very pretty but I have issues with the formula. Firstly, the colour is a deep, blackened navy shimmer. It looks black in dim lighting and a beautiful glowy blue in brighter lighting and sunlight. It is very pretty. The formula applies easily, it was a little runnier than my other Essie polishes. I only needed two coats to reach full opacity. It applied without streaks or bald patches, though I definitely recommend using thin coats in order to have greater control of the polish. It dries to a slightly dull finish so I highly recommend using topcoat for shine. The polish only wore nicely for 2 days before chipping when paired with base and top coat. I find this unacceptable when I can usually get 5 days from an Essie mani. It also stained like crazy, even with two coats of base coat underneath. It stained my nails, cuticles and skin. I had to use quite a lot of remover on my nails (which is very drying for the nails) and then follow up with soap and water. It takes a few days for all traces of blue to fade. The staining issue and wear time are the main reasons I do not recommend this polish.
