I love how they throw "postnatal" in there as a way to try to legitimize the grossness. Yes, some women have loose skin around the abdomen after giving birth - I know a few. BUT if they were thin before and during pregnancy, that skin is just that - a little bit of skin that's now looser. It may hang slightly over jeans or something, but it cannot by any stretch be called an "apron." It CERTAINLY does not hang enough to lay on top of their genitals or cause  serious issues. So screw them for trying to lump women who do take care of themselves  and have some minor changes from birth in with fats who have abandoned all self-control.
