I've had some hit or miss luck with some of the maternity clothes I've picked out. However, Gap & Target seem to have cute, inexpensive stuff. The best thing I've found so far is the Gap Maternity Tunic. BUT, they seem to have sold out on the website. I did find one additional for sale on ebay (at a way better price than gap, too). Enjoy:
