^^It is about how men think, and men and women are allowed to find certain sizes appealing no matter. Attraction is a matter of preference as we see from some of the comments on this thread.
Women and men should be comfortable being who they are no matter their size. I believe the catwalk should represent different sizes and shapes as that represents the western world we live in. The skinny model you see on the runway (usually skin and bones) doesn't represent the majority of western women. This is what the article is talking about.
