Buying clothes for mom bod

So before my daughter I was a rail... I could literally wear anything and tight shirts were not an issue.

Now I am struggling to find clothes I feel comfortable in with the stomach pudge.

I'm still pretty small, but I no longer have a flat stomach.

Does anyone have any good clothing store suggestions that are good for typical t-shirts, Jean's, etc. I dont wear clothing that are very stylish or "in" I am a tshirt or tank top girl.

Any ideas or good store suggestions that are not too spendy?

Thanks!
