Here they are on the nail, all 3 coats with no base or top coat:
The Claire's surprised me by drying nearly matte--definitely need a top coat with that one, unless matte glitter is your thing. I could probably have stopped at two coats for the SH Xtreme Wear and the Orly. The Essie was definitely the chunkiest and sheerest of the lot; I do not know how this mini labelled "Rubies Slippers" would compare to a full size Ruby Slippers. You can see the textures in this shot (as always, click to see bigger):
I put one coat of SH Insta-Dri on just the Claire's finger and that shined it right up (other nails in picture below are still without any TC):
So, do we have any dupes here? Not quite. The Essie is unique. The Milani is a touch lighter than the SH, and the Orly is a touch darker. The Claire's, with top coat, is a touch darker still. Still, the four non-Essie ones are close enough that one wouldn't need all of them. My pick is the Sally Hansen, with Orly close behind.
As of now, I'm four short of 100 followers; when I get there I plan to have my next giveaway: a complete set of the Wet 'n' Wild Wild Shine summer collection as featured in this post. To enter, I'll be asking you to suggest a change you'd like to see to my blog, so start thinking about that, please.
