You know that is a hard question to ask from a female. I have many females friends and family that look good without make up. But we like makeup, nail polish and other girlie things. So of course I'm going to say they look better with it. I mean who can resist the newest lip gloss shade and blush. Ya know what I mean? :D
The Chinese women look better withot it, it only detracts from their natural beauty. My Caucasian friends, also look better without it, but good luck telling them that. They only care what the movie stars are doing, and they lather it on like shaving cream, so...
dude, all women look better with some kind of make-up on, even if they are the most gorgeous woman in the world, they become extra gorgeous with make-up because it enhances their features, if it's put on wrong then it actually makes them look bad though.
I know many guys here and in real life that condemn make-up on women or girls, but have you ever seen a guy follow or even make a pass at a girl that hasn't have make up on? No!
I for one like my wife to put on make up and enhance her features, it makes her look more lively.
I think on most girls, it doesn't make them look better OR worse. Although I kind of have a soft spot for how my girlfriend looks without make-up because that usually means we're hanging out at home all day instead of going anywhere. Fond memories associated with no make-up on her.
