Take a look at both of these pictures. What do you feel when you look at each?
I combined some of the most distasteful traits I could think of in the first picture and found a picture that contrasted each one.
The first picture is hot and dry, the dress is conservative, dark, shaded by an umbrella and hidden from the sun.
The second picture is cool and wet, the woman is dressed in a bikini, it's light, bright and wide open. :)
The point: Some traits are innately desirable.
