I understand that chinese sizing differs from American, I ordered a large and an extra large, the only difference between the two was the cup sizes. I am size 8 American and thought at least one would fit me well enough, I can't even get the swimsuit over my hips. The torso is super short as well, the suit itself comes up to the middle of my rib cage and isn't long enough to cover my breasts. In what world does extra large equal what would be a size 4?
