From my own observations, at least. I don't know about older women but girls my age (college) who have proven their size queens in one way or the other have this certain look about them. I can't really put my finger on what it is though. They're the girls who give off the impression that they like sex right when you first meet them. Don't confuse this with a "ho", that's different, these girls just have a kind of sultry, sexual quality to them. I've honestly noticed this, I'm not really saying it's actual facial features, just expressions.
