I want to start by explaining that I swim for exercise, not leisure. I wanted something that I could actually "SWIM" in, not just wade around in. That is why I opted for the higher waist option. I debated a lot on what size to order here. I opted to size up, as when I purchased them I was only about 5 months along, and hadn't expanded much, but I wanted to be safe and I figured that I would get larger, later. I'm a little over 6 months now and these are still huge. The are big in the butt/ thighs, and huge in the belly. The fabric in the belly is different from the lower portion and stretches easily, so they often migrate down and have to be pulled up. I don't know how I will feel a couple months from now, but I'll try to check in again. Meanwhile, order your pre-pregnancy size. Otherwise the cut and design are great. I have been wearing with a non-maternity tankini top. My only gripe there is not enough support up top. I would recommend pairing with a higher cut top/ razor back if possible if you plan on swimming for exercise.
