She looks great in this pic to me. Still doesn't seem "plus sized" to me but I guess compared to the current standard of beauty, she fits that mold...dunno. She has a pretty face and she's working that bikini.
I'd guess she's a small size 14, meaning that she's mostly too small for plus size clothing, but too large for so called "straight" sized clothing. It's definitely an improvement over having a size 6/8 model for Additon Elle.
