Let's assume that they're equally attractive. Which one would you (as a guy) be more drawn to? One girl is wearing nice clothes, and obviously put some time into her hair and makeup, the other has her hair in a ponytail and is wearing jeans and a t-shirt.
The one who is more attractive. Life isn't a walking contest competing with some chick who does the opposite as you.
Do the opposite of what guys say cause that proves to be the most successful. They say the natural one yet they chase or end up with the one plastered in makeup cause there's more to a girl than whether she wears makeup or not.
If they're both equally as attractive then the one in jeans and t-shirt why because she looks just as good as the other without putting much effort in so imagine how much better she'd look with a little effort.
