The second one looks like she's standing as straight as she can, back slightly arched back, and  sucking it in. She's also pulled her arm up to her hip. If she were to lower her arm and stand in a relaxed position she may very well have a roll going on there in the underarm/bra area.  I don't know if she is obese or not but she's got a bulge in the stomach area and is definitely overweight. I didn't downvote you, that's not my doing but the second one is definitely fat and I suck at identifying ham angles.
