And drawing a conclusion of them, based on them being a size 12, or whatever size they may actually be, is more of a reflection of the character of the person who is judging them, rather than the person who just happens to be of a certain size.
That's exactly the point.
It's bullshit like Luke's throw away comment, about her size, which makes women feel that who they are isn't good enough. It all contributes to distorted body image, insecurities and eating disorders. Personally, I think some of the sexiest people I know are the ones who are comfortable in their own skin, and their confidence radiates regardless of what size they are.
I'm pretty sure that girl would be really hurt if she ever found out she'd been the subject of this thread. And i'd ask others to consider how they'd feel if the shoe was on the other foot, prior to posting any pictures up.
