First, the material is wonderful. Supportive and double lined. Adjustable straps are a plus for petites. The shelf bra is sewn in securely to the inner lining and the construction of the suit is awesome. I’m in my second trimester (21w) and ordered a small which is my usual size in swimsuits (100lb pre-pregnancy). The fit is perfect right now and I love the cut of the leg. My only concern is that it won’t last through the third trimester. The external lining of the suit has the extra fabric in the belly, but the internal lining in the belly does not which makes me wonder if it’s going to be comfortable in another 8 weeks. Overall, I’m really happy with the quality of the swimsuit so I will keep it and hope it fits through the summer! Will definitely purchase again post pregnancy.
