Most guys on here will say no makeup, but most guys don't actually know what no makeup vs makeup looks like.
Makeup's only purpose is to enhance your appearance, and about 90% of western women use or has used it. It works. What men don't like is when you wear so much that you hide your actual appearance, what we do like is when you wear enough to accentuate what your natually strong features are.
I prefer makeup, and if you apply it correctly, you'll notice other men do too, whether they realize it or not.
I'm tempted to say I don't but, let's be honest, of course I do. Most men do and if not, why would so much time and money be spent on them?
As a guy, I'm pretty clueless about makeup but I do think that it can make women look much better. It can also make them look much worse if overdone. a lot of the time, you'd be fine without. You don't need to dress like a model 24/7, or at least you shouldn't. If you do use it, I think it's better to use a little.
I'd look at it this way: the makeup should help show what's attractive about you as opposed to using so much that your face is just showing us your makeup imho.
Dude, Whatever the heck she feels comfortable as. As long as you don't look like a umpa lumpa from Whores R' Us, Then you where as much makeup as you like to. Most guys honestly do not care. Whatever you want.
