Jin requested a comparison of China Glaze "Secret Peri-Wink-Le" and Zoya "Caitlin" so here it is, girlfriend!! They are very very different, but both very beautiful =)
Both took 2 coats to cover up the nail, both had wonderful formula. They are very different in color; "Secret Peri-Wink-Le" is just that: a periwinkle blue, while "Caitlin" is more of a mix of periwinkle and grey. It's also much darker in hue.
So what do you think? Do you need both? =))
