Aesthetics never did last long in my heart, so if I'm attracted to someone merely because of their looks, their stature or their place in a social chain, my initial feelings aren't going to last a great deal of time. Regardless of what people may think, I'm one to look at people in the long run, if I think they're just going to be a short term friend/girlfriend I'm not going to put my heart on the line. Life experience has led me to learn that not everything will last forever.
More on topic; I'm not one to have a "type" as such, however I do have people I have been attracted to with some common reasoning. I have fallen for people who have been really beautiful, in saying that though, I'm not sure I'm always looking for that person who's typically beautiful and flawless, I'm looking for someone with a little more diversity, beauty that doesn't reside on the face of cosmopolitan, you see those women every day in the media, I wouldn't be attracted to someone that seems so plain in sight due to being just a typically pretty person. Though I do appreciate "good looks", I'm not sure every person's view on what is beautiful and what isn't, have a common state.
Inner beauty is most important, though cliché, if you're looking for someone in the long run, then looks aren't going to keep you interested. Though most of all, I would fall for someone, that could see me for who I am, who could appreciate my love that I show them; someone I could make happy and that could make me feel that way in return.
