I have been petite for my whole pregnancy but haven't been able to fit into my regular pants since quite early (around 3-4 months). NONE of the Old Navy pants fit. The elastic on the side panel pants gaped and the elastic puckered in a way that made them fit uncomfortably. None of the dresses I tried on fit—they were too baggy in the top and too tight through the hips (and to be clear I am NOT at all hippy). I found one plaid shirt that I loved, and that fit well but out of everything I tried on there, that is all I bought.
