We all go based on looks at the outset, because that's the first part of a person we see before getting to know them. If I think she's attractive, then I'll talk to her and see what kind of a person she is...if she's kind and smart, with a good sense of humor, then that's really about all I need. Appearance is *a* factor, but for me, it's not the main factor. I'd rather date an average or decent-looking woman with an amazing personality, as opposed to someone who's ridiculously hot but has no personality to speak of.
A collection of everything. Looks matter, because that's the first impression I get of anyone, but if it's not backed up by personality, then it's not enough. Likewise personality can make an average girl more attractive.
A decent dose of confidence combined with a fun but kind personality, plus a slightly rebellious side, and decent looks (but not overly high maintenance) ...that's what I look for. (Damn, I'm really quite picky!)
I look for a Personality that is compatible from mine but not a female version of me. I want a girl who is smart, likes my humor and is not scared to get her hands dirty once in a wile, but still has an air of elegance.
An average body is OK if she has a pretty face. There's such a wide variety of appearances that I'm attracted to it's not even worth laying out. I'm not so much into fat girls though. I used to be fat and it takes me back to how bad that was.
Her personality is so important. I have to be able to laugh with my girlfriend, and she must also be able to take a joke at her expense as well as give it back to me. It's just my sense of humor and I feel closer to people I can joke around with. It's a big part of how I cope with hard things in life too, self-deprecating humor.
