I discovered this combo by chance and decided it looked so pretty that I had to put it on immediately... Let's have a look!
Two coats of royal blue as base, then however many coats you need until you're satisfied with the amount of glitter on your nails. I did one for most nails. Everything in Which Is Witch? reflects in all colors of the rainbow, so this is very glittery. I love it. It's hard to get this to be smooth since it is, after all, a glitter polish over a textured one, so I would advise you just leave it a teeny bit gritty.
