I can tell quite obviously from the fit on the model that on my 5ft 2, size 8-10 frame the dress would have that frumpy "just grown out of it" look 
I'll never find my body shape represented by a model. For a garment to look good would make it too short for the majority. That doesn't mean my size is shamed.
The models look tall, slim and healthy, not overly thin/ gaunt.
