This is one coat, with topcoat. Denim is a gorgeous, rich blue, with lots of shimmery silver particles in it. It's not sparkly at all, but the shimmer really adds depth to the blue.
Coverage is really good - one coat was fine (although I did add a second the next day to cover the tip wear). Denim dries matte, which was also a nice look, but adding topcoat really makes it come alive.
I wore this with my latest bit of nail varnish jewellery, a ring made with Barielle's Elle's Spell (which I posted about here). I LOVE Elle's Spell, it's such a gorgeous colour. This is about five coats of Elle's Spell! I love how it moves between red and gold and greenish orange in the sunlight.
See? Isn't it pretty?
