I can't remember the brand name, but the line at JCPenny's was wonderful and cheap, I was actually upset that I couldn't continue to wear some of the stuff after being prego, I got some awesome sweaters and shirts that I adored! At Motherhood you can find some cute stuff on clearance and Target is a good option too! The "band" wasn't that prominent when I had mine, but seems to be a hit, so go for it!
You may want to consider getting some regular stuff just in larger sizes as you may have a "transitional" period after the fact too! My friends and I did that and just rotated all the clothes, between 2 summer girls, a fall boy and a winter boy, we had an entire year's wardrobe of "too big" clothes, so that we didn't despair that we couldn't fit right back into our "regular" clothes.
Good luck and continued success to all of the forumite "ovens!"
