I'm 5'6 and my measurements are 40-34-42 I am normally between L and XL. ordered size XL and got it over my hips, it fit ok in boobs but the cups run a bit small. I'm a 36DD. Could not get this to zip because it was too small & the thing is even though the corset part was too small it was a bit baggy in the hip area so it's like the dress isn't proportional. But it is pretty otherwise, train is very long and I have long legs. Returning.
