Yeah I feel so bad for the model.  She's not underweight.  Her bmi is hovering around the 18-19 range, which is low, but she's only seventeen.  From the front she looks fine, which you can tell from looking at the rest of the ad, it's just that one angle that looks different. They probably made her cry.  Middle-aged fat women making a teenage girl cry because she doesn't fit their body ideal, all the while crying body-positivity.  How pathetic.
