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.
Most Helpful Girl
I think most guys will be more attracted to whoever's prettier. A pretty done up girl is hotter than an ugly casual girl, and vise versa.
Honestly, I see far more girls who don't put in enough effort because they think they're naturally attractive than the opposite (girls who would be prettier if they put in less effort)0
