It is also a commentary on entitlement considering she is bitching for not fitting the mold that modelling agencies demand. Adapt or fuck off, that is how it works in life, and in her case she will continue to expand because oppression or whatever shit they come up with.  Moreover, we also see the age old theme of them misconstruing objectivity and subjectivity. "They see fat, I see perfection" they are mad because an agency HAD STANDARDS and respond with an equivalent of "we I THINK I AM GOOD" That is not how logic works, that is not how success is earned.
