10-12 isn't really big. Marilyn Monroe was a size 12. 12 is by no means skinny, but it is far from being fat, especially if you're on the taller side (5'8 and above) The modeling industry nowadays is unrealistic and skewed and they will tell you a size 12 is plus, but it's not.
The gut thing is definitely an issue though. I mean, having a perfectly flat stomach like a Victoria's Secret model is pretty hard to accomplish and normal people usually have a bit of a stomach, especially if they bend over and you can see the stomach squish. But in the first Easter picture, she appears to have no waist and is pretty much cylinder-shaped. Definitely something to be concerned about. I also noticed in her Lum pictures (that's the character in the tiger bikini, right?) you can really see how fat she is in that picture where she is showing her ass to the camera, you can see two rolls of fat on her back, further emphasized by her bikini top cutting into her flesh and how much it is cutting in. I'm not skinny, but my back has NEVER done that.
