I'm conflicted. The plus sized model is a very attractive woman, but... the rolls of fat don't look healthy or athletic to me. Not sure if the modeling lifestyle at any size is compatible with being athletic. I remember when I was in high school, a couple of my friends took a modeling course and I went to the runway show. It was really creepy.
As someone who is smaller, take this as my opinion. I do think, though, that clothing manufacturers should take the plus size market seriously and should have the same choices as "regular" sizes. And they should remember that short people buy clothes, too, no matter what their weight is.
