There's a bit of something called "angles" going on here. Notice how the first photo is zoomed in more than the latter two (thus making her look wider). In the third one, she has her shoulders raised higher and (I think) is stretching out her torso. Same girl in all shots though, I believe. (Similar leg mole/spot.) And aren't elbows supposed to be around the bellybutton??? Mine are, at least.
