Swatch in sunlight
I've applied it here over my usual taupe everyday eye (Sue Devitt Surat pencil and Lonely Splendour eyeshadow) - patted over my lid with a MAC 239 eyeshadow brush. It gives a little sparkle that catches the light and brightens the eye. I think this is just about daytime appropriate applied subtly, and you can pack it on for more glitter. It does tend to migrate onto cheeks as the day goes on - looking either like a sprinkling of fairy dust or glittery dandruff, depending on your viewpoint.
