I really wanted to love these. I bought 3 because I have a hard-to-find bra size, which means finding a nursing tank with enough support is almost impossible. SO, this is great because it just hooks onto your bra and instant nursing tank to cover your torso while nursing! It's ok, but the fit is terrible. It rides up constantly, but falls down in the back because it doesn't attach to anything in the back. If you never moved, it would probably stay in place and be fine. Other sites/reviews rave about this tank, but I just stopped wearing them because I hated that they never stayed down. I thought about getting a bigger size, but then the back would probably never stay up... If you don't have a very curvy waist/hips maybe it would work better?
