Pay attention to a small detail, that can drive me crazy however. The suspension the lady is wearing or black in some photos and white in the others. So what does this mean? Yes I think you are right, could be these are not all the same model but two different models posing in a same setting at a different time. Since the last photo was the only one I could find from this model I have attached it to this post, perhaps in time I will stumble upon others and be able to give her a single presentation.
