I ordered this suit at 18 weeks and I'm now 27 weeks. I thought no way it would continue to fit, but it is! The belly wasn't baggy when I was smaller but is still allowing room to grow. The breast area is supportive enough for me. Some reviews want more support in the tops, but for a lap swimmer, you don't want extra water logged material up there. I'm a lap swimmer (former triathlete). 5'9", 155lbs before pregnancy, 34C, and size 10 in pants. I ordered a medium top and large bottom (typical approach for me). It's still fitting great, straps and neck are really comfortable, and I don't even notice the suit while I'm swimming. The construction is solid and doesn't seem like it'll fall apart. I definitely recommend a 2 piece suit when pregnant! It's so much easier to get on and off. Lastly, it's super cute to boot and will probably be a usable swimsuit post pregnancy!?
