I read a few pages and might be the only one out but I actually love the 163! Sorry for the late post, but I managed to snag the last one when I picked up the Marilyn collection and Copper Beech just arrived yesterday. I'm NC25 and it looks great, nothing too dramatic but an everyday contour. I know I can apply more and heavy for a night out but I don't see any problems with it. The only question I have is that paler girls seem to be using Coffee Walnut which I believe is darker, so should I have gotten a even darker shade?
I also love the 163, so you're not alone;)
I'm NC15 and use Coffee Walnut, but I don't apply much. If Copper Beech works for you stay with it. The only lighter colour is Pure Sculpture, but that one was just too orange for me and that's why I went with Coffee Walnut. I might have gotten a lighter version if it was available, but since I don't have problems using something with a light hand I'm totally ok with this.
