I guess it depends on what her goal is; what she is trying to accomplish, look pretty, sexy, like a clown, or just slutty.
It also would depend on how ugly she is and how much work is needed to get her to look better. (Just joking here)
Seriously, I personally don't like seeing a lot of make up. I think women have a much different opinion of themselves than what the rest of the world is seeing. I have witnessed many beautiful women, that wouldn't have needed any makeup degrade their looks by covering their face with too much makeup or the wrong color combinations.
The bottom line is, less is more attractive to me. I like seeing the beauty of the lady. One more point is if it is someone that I am going to be kissing, I really would rather kiss her skin before having a mouth full of chemicals. Sorry but women have been fooled into believing that putting all the different makeups on that they will be more stunning. Someone lied to you. Show your true beauty, it is much more attractive.
