Another finish I love wearing in the summer are holos.  They’re perfectly suited for sunny weather!  Milani Cyberspace (3D Holographic) is a light blue holo:

Picture taken in artificial light.  (I didn’t know the sun wasn’t gonna come out today!  Normally I’d opt to shoot in natural light, but I wanted to show the holo-ness, so I shot under a halogen light.)  This applied well, although I needed three coats for full opacity.  The holo effect is understandably subtle in low indoor lighting, but it really comes alive in bright light and sunlight.  And I love this pretty shade of sky blue!  I paired this with Sally Hansen BLU (HD) on my toes.
