I wore this over Borghese Trevi Gold and it's only one coat. I've read that KleanColor has a really strong odor. Now I either have a defective nose (I don't) or I just don't mind the smell. Actually I kind of like it but, to me, it's not as strong as what I thought it would be. *shrug*
I'm going to have to explore this brand some more. Any suggestions on colors?
