Don't know if they have them in Houston, but there's a consignment chain store called Kid to Kid that resells maternity clothes and they had a couple of plus size tops when I looked. I got a great top for $3! Call around to consignment stores in your area and see if they resell maternity clothes.
If you can sew and know how to adjust patterns a little to fit a plus size figure, or are willing to hire a seamstress, I saved tons of $$$ making my own maternity clothes. Patterns are woefully scarce, but most pattern companies have a few. My favorites came from Butterick, Kwik Sew (very cute nursing nightgown pattern), and Burda.
Also, try Craigslist. I saw lots of plus size maternity clothing offered for super cheap, but someone always beat me to them! It's worth a shot, though. Good luck!
I'm not from Houston, but I am plus sized. To be blunt, I found jack squat in retails stores. I bought a lot of my stuff online or made it myself. Target's not going to fit you if you're above a size 16/18.
And Target might not fit even if you are a 16/18, their sizes are all over the place. So is Motherhood's for that matter, I've got tops from there ranging from L to 3x!! Old Navy's pants I like, but their shirts tend to be WAY low cut.
Depending on how big your belly gets, you might be able to get away with just regular clothes if the cut is right you might not even have to go up a size. Especially since long tops seem to be in style right now, I have several non-maternity empire waisted tops that work. I just bought another cotton one at Macy's yesterday (where of course almost everything is always on sale).
Haute Mommies and Bella Babies in Clear Lake has a decent selection of plus sized maternity clothes (cute styles too.) You can also shop the website at www.HMandBB.com. Congratulations on your new addition and good luck!!
