Ok,I'll bite ...
Physical appearance lights the early interest. Doesn't have to be a model, but must send the message "I take good care of myself ; I like to stay attractive ; I have a decent level of self-esteem; I have good taste.". Hair, eyes and lips are the main physical traits I look at.
Once that spark has been lit, come the personality traits that I consider most attractive:
Being down-to-earth and laid back. Being intelligent. Having a good sense of humor, while keeping the good taste. Having strenght of character - honesty and loyalty. Not being afraid of displaying affection and accept it when is given to her. Being supportive and compassionate.
Having a knack for artistry and being a neat, organized person are a BIG plus.
