Why not to believe model's measurements

(click the picture to view measurements) 

I've been looking up the measurements of models for a long time, comparing what makes their bodies look the way they do compared to me or to other people. However, I've always had a doubt as to whether the listed measurements, heights and weights were accurate. But really, why would they lie? All the women are obviously beautiful and confident with their bodies, so what would be the reason they would need to list them all as the same or lie about it? 

If you look at the picture above and compare the models I chose, specifically compare Miranda Kerr with Karolina Kurkova. Their hips are the same size. Their waists are only half an inch different.

REALLY? Adriana Lima's hips are BIGGER than Karolina Kurkova's?

Just Sayin'.
