Men really misunderstand the subject of makeup.
It's not about pretending to be pretty, it's about war paint.
All kinds of civilisations have used war paint. Makeup is a gentler form of war paint, and is the brave face women wear in public. It's not just to attract men, it's to appear socially acceptable, win the appearances battles at work and other things like that.
If a woman has worn makeup to go on a date with you, you should be observant and see what she's saying. Soft makeup (pink, gentle browns) means good intentions. Hard makeup (red lipstick, red fingernails, obvious blush) means she's after your scalp
