Well, the obvious is that different women find different things attractive.
Just as some men dislike flat-chested girls while some dislike big chested girls.
But with most women it's not the looks themselves that make a man attractive.
Women more then men have more attraction to specific types, and that's more in the sence of the man as a whole. The attitude, the body language, the clothing style, the personality, the flaws and the body.
The types (almost stereotype, especially when it comes to fictional characters) like the wounded soul that needs love, the wildboy who needs to be tamed, the quiet intravert who you can get to open up, etc.
You especially see this when talking to girld who are very into David Tenant or Nightcrawler, they focus more on the style and personality than their looks (that plays a factor also, of course). Note that Im just using these as examples, mostly because of their popularity.
...and men are of course interested in personality and that stuff too. but what we find attractive is often much easier to quantify.
I personally really like the manicly happy girls, you the type that makes you smile...
Yes I want to find my own Pinkamina Diane Pie.
EDIT: Im Bisexual, so Im not sure if my comment really counts if you don't want to hear from any women (or people who are interested in men in general).
