The thing with "profeSSional model London Andrews" is that even her knees are fat.
And it's everyone's choice how much fat you carry on your body, but she's clearly done lipo on the stomach or/and injected her own fat to other places. Because when you're heavy like that - you can't have tiny waist and flat stomach.
Either it's just heavy retouch, which doesn't always help, like on the "Curvy Mag" photo where her cottage cheese textured skin is blurred but the belly still touches the ground.
So when you look at professional plus size model Ashley Graham you must understand that her stomach is clearly done, and her jawline and cheeks are done too, because when you have amount of fat like that your bone structure is most likely hidden behind it.
Same thing with the fashion top models today - they are skinny af, but to match the modern standards they get fake curves in right places while staying skinny in other right places.
