Prepare yourself for too many pictures of this one!
Also, my apologies for not getting proper bottle shots of all the polishes involved.
Okay, so are you wanting to know what I used for this?
I started with Cult Nails Nevermore. Then I added a coat of Ozotic Pro 528.
After that, I used Lynnderella Bride of Franken for extra blue iridescence.
The last polish I added was Lynnderella Shape Shifter (newer version).
I finished with two coats of Gelous (three even just on one nail where a star glitter was in a precarious and poky position) and then Sephora X top coat.
