Jodi arias is a great example of how voice, tone, demeanour and the like can add or detract from sex appeal
Arias could be decidedly underwhelming looks-wise sometimes, but get her in an interview where she had incentive to impress and she was sexy as hell (putting aside the fact she is a psychopathic stalking murderer with huge curtains just for the minute)
Whereas the dancing milf Finish pm is the opposite: seriously good facial features and eyes,but as soon as she opens her mouth it's like wtf, hello robot drone
