For Christmas I got a new nail polish from O.P.I Cuckoo for this Color, a fab green that looks great with a black outfit. I wanted it for some time so I was pleasantly surprised when I opened the present! I've also been looking for the perfect grey polish but it's not as easy to find (or maybe it's just me being fussy). However, a friend of mine and I found a cool vintage grey color Miss Stone Heart at H&M's own makeup range for the really nice price of € 4! The search isn't over but for now, this grey colors my day! What is your fav nail polish color?
