I also layered two coats here over white and black cremes, Cult Nails Tempest and Nevermore. It's funny that I chose to layer it over a green above and when layered over a black, the crystals reflect to appear green :) The formula is on the thick side and I found it a little tricky to make my layers even when I tried to paint on the second layer too soon, so give yourself adequate drying time between coats for best results.
I like the idea of the Sugar collection from Ozotic. I love the celestial pale yellow almost gold of this shade. You can buy Ozotic Sugar 904 online at Picture Polish's Australian website for AUS $12, on Harlow & Co for $14.50, or on Llarowe for $14.50.
