A white is white...or so a man would say, but WE know better. Although even hubby was astonished at the difference. I held my nails up and he asked, "Why are those whites different?" So if a man notices you KNOW they are different.
So, funny story, my friend over at Constantly Redone ordered Zoya Snow White and I ordered Zoya Purity. I wanted a soft and squishy white and she was looking for a stark, clean white. We got the opposite of what we wanted. Observe:
Nitty gritty - you can see from the images that it is, in face, Snow White that is squishy and soft and slightly less opaque while Purity is stark, crisp, clean and more opaque. These are both one coat over a clear base coat with no top coat.
