Patience,
I went for fitted tops during pregnancy. I found that I was able to wear regular tops from ATL during my entire pregnancies. They now offer maternity tops too. The stretchy material gave me a nice fitted look, which I prefer. Plus I had non-maternity tops to wear for the 4th trimester while I shrunk back to my pre-preggo size. Here is a pic of me at 35 weeks in one of the ATL tops I was describing. It's just a regular XS top. Something about the material just worked for me during pregnancy:

For skirts, I just made sure that my entire bump was covered. Also, if I was wearing, say, a maternity pencil skirt (I had one from Gap), I made sure that my tops covered the band. I would imagine that a banded top would work for pregnancy, plus you could scrunch and adjust the length(?). And if your baby gives you an "outie" like mine did, then the drapiness of the banded top may camoflage this. Try and see.
I found that for pregnancy #2, I relied on faux wrap jersey dresses and didn't bother with skirts. Just seemed easier, I guess.
HTH...and hope you're feeling better!
