I bought this in the 36F as reviewers were saying that the cups were coming up small and, indeed the F was a good fit but even so the cups were wrinkling on the top - very curious. In the main body of the suit the fit was just okay - could have been a bit tighter from waist to legs as it didn't really control anything. However, I really struggled with the back fastening which seemed very tight. In the end my husband had to fasten it for me. Even he struggled and he could see what he was doing. I don't see why the back fastening needs to be so tight, it makes little difference to the bra section at the front and just makes the back uncomfortable. I really can't be doing with this struggle every time I put the costume on. To summarise, from the front the costume looked fairly good but the back was not at all flattering, unfortunately this will have to go back.
