Fairy Dust is my 6 year old daughter's favourite colour! Agree with the previous reviewer; the purple is rather light (it's a jelly) and in bright light/sunlight, the pink shimmer and holographic glitter definitely stand out (not truly captured in my photo, which FYI is three coats). Haven't tried it as a topper but it could absolutely work as one. Only (very) minor issue is I dislike ILNP brushes (they are quite narrow and I find them hard to work with for getting smooth lines around the cuticle area); a matter of personal preference I suppose and not that big of an issue to deduct from the rating of the polish.
