Just attractive, I'd say hairstyle. A girl with a nice hair and/or hairstyle will make me not care about her boobs any day.
Personality... I like it when a girl is curious. One who wants to know what I'm thinking about, what I think about, and my opinions on any random subject she might be thinking about. I'm still looking for one, though.
Personally, the boobs is the most attractive part of the body. It is very unattractive when girls wear a lot of makeup. It's cool when they wear just enough to let guys knwo they like them
Personality wise, I like it when girls are passionate about what they do. They know what they want to do and love doing what they do whether it be for a cause or just participating in an extracurricular activity in high school or college. Obviously, It is very unattractive when girs are very snotty and rude to anybody.
