Yeah, I noticed. You and your fake tits.
First thing I will notice is if she has an "au naturelle" look. I hate orange girls and one with 4 layers of make-up. Then, of course, you would look to see if she matches what I count is hot/pretty/beautiful ( note I didn't say "if she is hot" because beauty is in the eyes of the beholder ). I don't think any guy can say he looks for personality first, because it isn't the first thing you see; however, closely after looks I would want to know what type of person she is - looks in my opinion count for face more than anything else, if she was a bit chubby but was stunning, then why not? ).
I like simple ( not stupid ) and decent girls who aren't obsessed with their outlook. Then you have the characteristics of her personality, but as long as she isn't ignorant and intolerant and can laugh at crude jokes, then it's fine.
