She can be plain looking without makeup and then suddenly be
unrecognizable with makeup.
For this reason I believe that some guys do not like makeup, comparing
it to false advertising.
As long as makeup is not overdone I think it is great.
Depends, some guys like girls who wear a lot of make up (but not those who look like clowns lol), some guys like natural beauty (but that is only if the girl looks at least decent without makeup I've noticed), and some like girls who wear a little makeup but not a lot.
Some like a girl with a nice natural look.
