Is this your first pregnancy? Because that sounds very normal, as the previous poster said. It took 9 months for your body to stretch out, and it's going to take some time to go back... but it will never, ever feel like it used to. My hips were definitely wider, and my tummy softer after my son, and that never changed.
You could wait and see how your body changes in a few months, or just go ahead and buy some new clothes for your post-baby body It's totally normal.
