I also picked up something that has changed my life when it comes to removing glitter polishes. Nail Pattern Boldness (I always want to type baldness!), Glitter-A-Peel. I first read about it on The Mercurial Magpie.
What does it do? It allows you to remove glitter polish instantly with no mess. You paint two (thickish) coats of Glitter-A-Peel and let it dry. Then paint your normal glitter bomb nail polishes over it, plus topcoat. Glitter-A-Peel will only last 2 days tops before pieces start popping off on their own. But since I change my polish often no issues there. I wore the dolphin polish above for two days straight, until I woke up with my pointer finger naked, it must of popped off when I was sleeping! To remove the rest of the polish, I used a wooden cuticle stick to loosen the polish a bit from the side and then I just peeled the rest off. It comes off in one piece. No more scrubbing you nails with acetone!
Failed Easter Mani- but you get the idea of how easy Glitter-A-Peel removes once you've loosened the edge with your finger or a wooden cuticle stick.
