I would like to say "none at all", perhaps because I know not to expect her to put any more effort on her looks than I do on mine.
But given that aside, by purely aesthetic preferences, minimal is perfect. Enough to even out your skin. Much more than that and I start to feel uneasy. The biggest drama queens I've ever known were heavy makeup wearers. And perhaps that's an unfair prejudice, but it's about like what women would think of a man with big glasses and a mustache. You don't ASSUME how he is, but you feel uneasy nonetheless.
Minimal or no makeup can be nice because of the realism and down-to-earth vibe it gives in comparison. There's something nice about seeing a girl's actual face.
The minimum that you can get by with for the situation.
On an average day, eye liner and lip gloss is plenty. Obviously, on special occasions, you might want to wear more, to go out to some fancy event, or for a photo shoot or something, and that's fine, but I strongly believe that most women wear WAY too much makeup WAY too often.
I like very little to no makeup on a girl. If I'm dating someone, I want to actually know what she looks like. If you have enough makeup on to look like a clown or a portrait that used oil pastels, those are signs you've used wayy too much.
No make up, please. At the VERY most minimal, but ya, basically none is best. Embrace your natural appearance. Doesn't mean you have to be lazy about being clean or minor things like combing, but you don't need make up.
It's interesting that most guys say they prefer "no makeup" yet if they see an average girl with legitimately NO makeup on, they would more than likely not be attracted to her.
I feel like when women wear minimal makeup, guys assume she is wearing none and that she naturally looks like that. But, I could be wrong, that's just something I've noticed from guys I know in real life.
Guys think they want a girl with no makeup or a "natural" look, but if you start questioning them on what they think a natural look is, they'll usually list off hot celebrities who wear tons of makeup that's applied by a good makeup artist.
I just answer questions like this to see the answers.
Lol, I am not a guy...but I believe most like it for special occasions or in photographs. But not on a daily basis, especially since they like to get all touchy feely and suck face. No dude needs smeared lipstick or gloss on him. No dude wants nasty goo foundation all over him. And who wants to look at racoon smokey eyes very day? Most dudes don't even like cake. They can tolerate mascara and a bit of eye liner. No face makeup and nothing too heavy on the eyes. But, if I was potraying myself to impress guys, I wouldn't do what I do. But I do what I do because I love it. And that's how us girls need to start thinking. If you hate makeup, don't wear it for him. Just make sure you don't wear ut for yourself. Same thing goes for if you like it.
I think they prefer make-up they can barely see is on there. Guys don't know that that's still a lot, but it should be just enough to fix your flaws and enhance your eyes. Some guys who have lived with their girlfriends might know how much work even that is.
