I'm really confused here actually. She looks kinda fat in the hips and waist but has a very obvious collarbone.  Her face isn't particularly pretty but it's not particularly fat either. I'm gonna go with "this is why healthy BMI is a range" for this one.  She may very well be 138 but that could be too heavy for her.  Most people start looking fat as they approach the upper end.    I've known women who look not unlike she does and were about the same BMI. I saw the number on the scale myself.
