Midsummer Night is a cobalt blue jelly with color-shifting shimmer. Holy smokes is this color amazing! I loved it in pictures loved it in the bottle and love it on my nails. Because it is a jelly it's definitely on the sheer side. I opted to layer it over Revlon Royal to give it a bit more depth and opacity. This is one coat of MN over two coats of Royal.
I really have nothing more to say about this polish other than... get it. You need it. You know you want it. I circled around it for about a week and I am so glad that I didn't talk myself out of buying it.
Midsummer Night is a Limited Edition polish so get it while the getting is good! It is sold on the Cirque website and retails for $13.
