Guys, what personality signs/behavior signs tell you that a woman is submissive?

I'm curious about what men look for specifically, to be able to identify the submissive girl most seem to want. Do you go for the quieter girls who don't give their opinions as much? Are there body language cues? What gives you the signal that she is submissive, while you're getting to know her?

If you prefer dominant women, please answer as well. But as a woman with a "dominant personality" myself, I kind of already have an idea of why guys who like my personality like me. I mean, there's not much submissive about me as a person - I'm very expressive and assertive about what I want, my opinions, probably get into too many debates, I'm very talkative and loud, laugh a lot and make jokes, kind of an open book but I can also be guarded and defensive, stubborn, very strong in my convictions and not open minded about serious things. I tend to lead conversations without realizing it or even when I don't want to, always stick up for myself and others if I feel like it's safe to do so and someone is being treated unfairly, etc. There's not much about me that screams submissive or passive. I would assume guys just look for the opposite traits to mine, but I could be wrong. How do you tell she's submissive?
