Grey Friday isn't all that. You could easily get the look by mixing a really light colored frost with any black lipstick. Estee Lauder did something similar last year that was a bit sheerer, called Gunmetal, that was handier than GF, which was a bit too opaque to layer over - all you could do with it was mix it, rather than layer it. I still think Firm Form is so much more beautiful than GF. I can't wait to try Hautecore in person to see if it topples Firm Form as my favorite black, but no matter how nice it is, I'm not sure it can win over Firm Form. The only thing that maybe could is if MAC would do an amazing metallic frost like Dominate in a pure black - now that would get my legs trembling a little bit!
