I ordered this swimsuit in a large, I usually wear a medium/large - for reference I am 5'7", 165 pounds, hourglass body type and wear a 36C. The suit was a little tight for me, dug into my hips, butt, and back. I'd recommend going up a size. I absolutely love the style with the mesh insert and high neckline. It is a very sexy swimsuit while still making you feel covered up, takes away the worry of spilling out of a swim top while still showing some cleavage. There's a cute band underneath the breasts that helps contour and hold the girls up which is a great detail that I hadn't really noticed when purchasing the suit. There's not as much ruching on the abdomen, as other suits I've tried on but it does the job of slimming and hiding my little tummy pouch. Overall, it's a great suit, just be careful on sizing.
