The colour I have is Sugar Frost, which is from the mini Caviar Eye Stick collection ($45 for 4 shades from David Jones) which I wear 2 ways.
1. Inner corner highlight
I highlight the inner corner of my eye to instantly fake brighter eyes, ones that have had at least 12hours sleep! Normally when I highlight the inner corner of my eyes with any other shimmery shadow by lunch time it wears off and the effect is lost. This stays on until I'm ready to remove it.
2. All over the lid as eyeshadow
Have you tried the Laura Mercier Caviar Eye sticks? Have you tried anything else from the brand?
