The Boob Fast Food Nursing swim suit is very forgiving. It took a while to wiggle it over my enormous belly, but once I got it over, the suit is very comfortable. I like the option to adjust the leg length and cleavage dip too. When I first put it on it wasn't very flattering, but once I took the legs up and dipped the cleavage it's way cuter. I ordinarily wear a medium in Boob clothing and have a 36D chest. I purchased the medium in the swimsuit too and it fits over my 9 month belly. I'm sure the side ruching helps!
