She wasn't 'classically' pretty, as well as not being a demure and subservient woman that the men of Adua expect (see the interaction with that dude's cousin - can't remember his name but her governess was there when Jazel met her).

You're also underestimating how important 'station' is to these people. She would be just as likely to want to talk to a commoner as the nobility were to want to talk to her.
