"Would you rather watch old and ugly then?" - Bloody hell, I can't believe anyone would say that.
I would rather watch women who reflected the massive diversity of woman around me: young, middle aged and old, plain and pretty, fat and thin, not some identikit of young women in tight clothes.
^^ this.
It is quite possible she is perfectly happy wearing these clothes to do her job, and it's her choice.
I'm cynical enough to believe, however, that she got the job because she's perfectly happy to wear these clothes to do her job, not in spite of it.
Really, can anyone honestly say they think the appearance the majority of female tv presenters is a reflection of the way an average woman looks? I don't. It's blatantly obvious that looks are at least no.2 (if not no.1) on the list of attributes necessary to get a job on telly if you're a woman these days.
