Isn't the dress from the players party a bit much (or a bit not enough) for a girl her age? Maybe I'm just old-fashioned in more ways than one, but I wonder what's the image she's trying to portrait dressing like this. Of course, she shouldn't dress like a nun, but this seems like something you'd expect on a girl 5-6 years older. I know tennis is business and that sex sells, but Donna is still a minor and will remain to be one for quite some time.
Nothing wrong with the dress. Doesn't show off too much. Girls wear much less to school formals
