I bought this suit for a trip to Hawaii during my 3rd trimester. I had a one piece as well, but in the two weeks we were there, I wore this one every day but one. I typically wore the bikini top but the tankini top was awesome for the road the Hana- so easy to put on with a pair of shorts and hike into the waterfalls. This is the most comfortable swim suit I've ever had. Even with my big 32 week belly and body, it never rode up the backside and the bikini had awesome coverage. I couldn't wear my pre-pregnancy bikini because my boobs were too big and it was a bit scandalous. It was easy to get off and on- even when wet- which is key when you're having to get out of the pool to pee every two hours. All in all, probably the best swimsuit I've ever had and I'm secretly hoping it'll still fit next summer when I'm no longer pregnant.
