Barry M Navy & OPI Last Friday Night, Layered - NOTD
I have layered Barry M's Navy which is a navy polish with electric blue shimmer (NOTD here) and OPI's Last Friday Night which is a blue jelly packed full of different shades (& sizes) of blue glitter. You can see Last Friday Night on it's own here. There's a good bottle photo of LFN on that NOTD, I wasn't able to take one for this post as I've nearly finished the bottle.
This is one coat of each before I've put my topcoat on. It makes such a difference to LFN when it's layered over a darker colour. The light blue glitter stands out so much more! I've found blue and black work best although it looks good on a lot of other colours.
