Thick/thin Models

Plus sizers are constantly told that their figures are hard to design for.   Well, I have a similar thought when it comes to really thin women.  

This photo shows a model wearing pants that appear to be so tight that she can't stand with her legs together.  Don't tell me that models and women per se don't prefer to stand with their legs together.   So many models and so-called celebrities stand like little children caught out doing something naughty - where did that stance come from?

Why isn't it OK for a woman to have flesh on her arms and legs?   This photo to my way of thinking looks ungainly.  But then I might be old-fashioned!
