Naughty Nautical is from Essie Summer 2013 Collection. It's a teal, shimmer polish. The shimmer is more noticeable in the bottle than it is on the nail. The formula is pretty good. It is highly pigmented, so you will get perfect opacity in 2 thin coats. But the formula is a little thin, making it easy to flood cuticles if you are not careful. I was worried that it would stain my nail, but it didn't (it very slightly stained my cuticles upon removal). Essie polishes have 2 different brush sizes (I think I have read somewhere that thinner brushes are produced in the US and wider one in Europe, but it could be other way around). My bottle has a thin brush, but I prefer their wider brushes, as I have wide nail beds. If you are buying from places like TKMaxx/TJMaxx, you could come across both versions and the easiest way to tell without unscrewing the cap is, if the name label is on the top of the cap the brush is wide. If the name label is on the base of the bottle the brush is thin.Despite the fact that the shimmer is not as noticeable I was hoping, it is still a very pretty colour and it suits my skin tone, so I would repurchase this polish.
