I have one Glamourmom tank and I found the band to be itchy and uncomfortable...too supportive I guess! The Target tanks are definitely not supportive, but I don't mind sporting the saggy uniboob for those first few months. I do have two fitted/sized Bravado nursing tanks that fit now, long over my belly, and I think I will use those more often this time. With it being summer, I just might feel comfortable enough to wear one of those without another top on. I definitely put a shirt on over my target tanks, my boobs will be bigger than a G cup when my milk comes in and it's not a pretty sight. If you want to try a Bravado tank, I bought one on babysteals not too long ago, but they usually cycle through and they'll probably come up again before we have our babies.
Ooo thanks for the babysteal tip!
