OPI's No More Mr. Night Sky is a pretty gunmetal silver with a fair amount of shimmer. I found that this polish looked absolutely incredible under bright lights, but in natural lighting it was a bit of a dud. Seeing as we're in the middle of Winter here in Ottawa, there's not too many chances for this polish to come to life under sunlight.
The formula of OPI's No More Mr. Night Sky was a bit thin, so I would definitely recommended using at least three coats for better coverage. I would also recommend using a top coat with this polish to help to further bring out the shimmers in this formula.
This polish just didn't "wow" me, which is a real shame because it looks so pretty in the bottle! However, there are so many other gorgeous polishes from OPI's Starlight Collection that definitely make up for this one!
